Merged gcj-eclipse branch to trunk.
[gcc.git] / libjava / classpath / NEWS
1 New in release 0.94 (UNRELEASED)
2
3 * The ASM library is now included. A separate copy is no longer needed.
4
5 * The setReadTimeout and getReadTimeout methods have been added to
6 java.net.URLConnection. They are now fully implemented for http URLs.
7
8 New in release 0.93 (Dec 8, 2006)
9
10 * CORBA objects that exist on the same virtual machine and only are connected
11 to another ORB are now accessed directly and no longer via network. It is
12 the same feature that RMI implementation provides. These faster calls should
13 be completely transparent, as the parameters are cloned, where required.
14 Currently the direct calls are only possible for the non-deprecated objects
15 that are connected to the ORB via POA.
16 * The 'javah' tool has been added. It requires the ASM library
17 (see asm.objectweb.org); it can be enabled with the --with-asm
18 option to configure
19 * Added the rmi and corbaname URL context factories for JNDI.
20 * Fixes in the JNDI InitialContext now allows to plug-in user implementation.
21 * Removed currentClassLoader method from
22 vm/reference/java/io/ObjectInputStream.java.
23 * Added firstNonNullClassLoader method to
24 vm/reference/gnu/classpath/VMStackWalker.java. VMs are encouraged to
25 provide a more efficient implementation.
26 * Added aton method to vm/reference/java/net/VMInetAddress.java.
27 * NetworkInterface has been implemented for systems that provide the
28 `getifaddrs' function.
29 * java.nio.channels.Selector implementations have been added that use
30 the kqueue notification mechanism on Mac OS X and *BSD, and that use
31 the epoll notification mechanism on Linux 2.6.
32 * java.nio has been refactored to support more non-blocking operations
33 natively. Blocking IO classes have been refactored to call
34 non-blocking classes. Non-blocking accepts, connects, and
35 scatter-gather IO should now be better supported.
36 * HTML support for Swing has been greatly enhanced.
37
38 Runtime interface changes:
39
40 * java.net.VMNetworkInterface and java.net.NetworkInterface have been
41 updated to keep native-modified state in the former, and to simplify
42 the native code in our reference implementation.
43 * gnu.java.nio.VMChannel has been expanded to better support native
44 non-blocking IO. Most native state data (such as file descriptor
45 integers) has been abstracted away into private state in the runtime
46 interface.
47 * gnu.java.nio.VMPipe has been similarly changed.
48 * gnu.java.net.VMPlainSocketImpl has been changed to remove some
49 functionality now provided by VMChannel; datagram socket-specific
50 methods have also been moved here, deprecating VMPlainDatagramSocketImpl.
51 * gnu.java.net.VMPlainDatagramSocketImpl removed.
52
53 New in release 0.92 (Aug 9, 2006)
54
55 * GConf is used as a backend for java.util.prefs. GNU Classpath
56 thanks to Mario Torre for this contribution!
57 * libjawtgnu.so has been renamed libjawt.so for binary compatibility.
58 libjawt.so should be installed in a VM-specific directory rather
59 than directly in /usr/lib. Proprietary VMs put their libjawt.so
60 implementations in VM-specific directories but search /usr/lib first.
61 If GNU Classpath's libjawt.so is installed in /usr/lib it will create
62 problems for people who use a proprietary VM to run AWT Native
63 Interface applications.
64 * The GdkGraphics2D backend has been made the default. There is no
65 longer an explicit dependency on Cairo, the --enable-gtk-cairo
66 configure option is gone, and GTK 2.8 or higher is now required to
67 build the GTK peers.
68 * A Mozilla plugin, 'gcjwebplugin', is now included. It introduces a
69 dependency on the Mozilla plugin support headers and libraries.
70 * New java implementations of png and gif imageio readers and writers.
71 * A tools.texinfo document has been created and now includes
72 documentation about:
73 * appletviewer
74 * gcjwebplugin
75 * jarsigner
76 * keytool
77 * Several new tools are now included:
78 * appletviewer
79 * jar
80 * native2ascii
81 * serialver
82 * keytool
83 * jarsigner
84 A new configure option --enable-tool-wrappers causes wrapper
85 binaries to be built for VMs that support the JNI Invocation API.
86 * We've imported the JSR 166 (concurrency) reference implementation.
87 * javax.sound.midi providers have been added to read and
88 write standard MIDI files.
89 * A javax.sound.sampled .au and .wav file readers have been added.
90 * New Java Virtual Machine Tool Interface header, jvmti.h.
91 * AWT peers for X Windows based on Escher (a pure java X protocol
92 implementation) have been added. So far it supports AWT 1.1 style
93 Graphics, image loading via ImageIO (PNG, GIF and BMP images in this
94 release), top level components as well as mouse and keyboard input.
95 It is capable of running many Swing applications. Graphics2D and
96 AWT widgets are not yet supported with this peer set.
97 * GConf based util.peers backend (see the --enable-gconf-peer and
98 --enable-default-preferences-peer configure options).
99 * Support for batch importing trusted certificates for use with ssl
100 connections (see script/import-cacerts.sh).
101 * NIO scatter-gather channel support.
102
103 Runtime interface changes:
104
105 * A new class, VMURLConnection, is used to implement
106 URLConnection.guessContentTypeFromStream. The reference
107 implementation uses libmagic (and falls back to doing nothing if
108 libmagic is not available).
109 * The method gnu.java.io.PlatformHelper.toCanonicalForm() has been
110 replaced with a JNI implementation of VMFile.toCanonicalForm() for
111 GNU/Posix systems.
112 * A new class, VMRuntimeMXBeanImpl, is used to implement
113 the low-level support of the runtime management bean.
114 VMs should use it to supply the input arguments and start
115 time of the VM. In addition, one of sun.boot.class.path
116 or java.boot.class.path should be defined by the VM to
117 support the optional boot class path access functionality.
118 * The Unsafe class was moved back to the place expected by the JSR 166
119 reference implementation. We've also added a couple other new VM
120 classes to support the JSR 166 code -- sun.reflect.Reflection and
121 sun.reflect.misc.ReflectUtil.
122 * Another new class, VMClassLoadingMXBeanImpl, is used to implement
123 the low-level support of the class loading management bean.
124 VMs need to supply it with information about how many classes
125 are currently loaded, how many have been unloaded and whether
126 verbose class loading output is on or off. Provision should also
127 be made for the latter to be toggled at runtime.
128 * VMThreadMXBeanImpl is used to implement the low-level support
129 of the thread management bean. Providing this interface requires
130 providing a fair amount of information about threads, including
131 optional time and contention monitoring, and instances of the
132 new ThreadInfo class in java.lang.management. getState() has also
133 been added to the VMThread interface; this is required by the bean
134 as well as java.lang.Thread.
135 * VMMemoryMXBeanImpl is used to implement the low-level support
136 of the memory management bean. Providing this interface requires
137 providing information about the levels of heap and non-heap memory,
138 and the number of objects eligible for garbage collection.
139 * VMCompilationMXBeanImpl is used to allow for optional compilation
140 time support for Just-In-Time compilers.
141 * VMMemoryPoolMXBeanImpl is used to implement the low-level support
142 of the memory pool beans. Providing this interface requires
143 providing memory usage statistics for each supported bean.
144 * VMManagementFactory provides the names of the memory pools,
145 memory managers and garbage collectors maintained by the virtual
146 machine. These are used to create the beans by the ManagementFactory.
147 * VMMemoryManagerMXBeanImpl and VMGarbageCollectorMXBeanImpl provide
148 low-level support for memory managers (including the specific subclass
149 of garbage collecting memory managers). The interfaces for these
150 require no more than enumerating the number of collections and the
151 time spent (for garbage collectors) and a relationship to the memory
152 pools (for all), along with a validity check.
153
154 New in release 0.91 (May 15, 2006)
155
156 * Experimental activation (java.rmi.activation) support, including RMI
157 activation daemon and persistent naming service tools.
158 * Experimental printing support: The API implementation of the javax.print
159 packages has been finished and work on the printing provider implementation
160 started. Currently supported features from the Java Print Service API are
161 print service discovery (CUPS registered printers), single document print
162 jobs and support for client-formatted print data. An example application
163 (see: examples/gnu/classpath/examples/print/Demo) has been added to show
164 the API usage for service discovery and printing of files.
165 * The GTKToolkit now gives access to the both the system clipboard and
166 system selection.
167 * Custom mouse cursor support has been added to the gtk+ peers. And cursors
168 can now also be set on light-weight components.
169 * Free Swing improvements: Support for OceanTheme has been mostly completed
170 and turned on as default Metal theme. X11-style Copy and Paste behavior in
171 text components with the middle mouse button. Support cursor changes on
172 various components when resizing. Support for Look and Feel window
173 decorations has been added.
174 * Updated locale data information to CLDR 1.3.
175 * Various bugs in Classpath's SecureRandom implementations have been
176 fixed; that class now respects the "securerandom.source" security
177 property and the "java.security.egd" system property.
178 * Support for assistive technologies has been added to AWT and Swing.
179
180 Runtime interface changes:
181
182 * A new class, VMArray, is now available which separates the native
183 array creation method from java.lang.reflect.Array.
184 * A new class, gnu.classpath.Unsafe, is provided for handling the
185 new low-level operations required by java.util.concurrent.
186 * The reference implementations of Method, Constructor, and Field
187 now have a new native getModifiersInternal() method. The public
188 getModifiers() method in each case has been rewritten in terms of
189 this method.
190 * The reference implementation of VMThread has been updated to handle
191 the new Thread.UncaughtExceptionHandler support.
192 * A new class, java.security.VMSecureRandom, is now available that is
193 used to generate random numbers for seeding cryptographically-secure
194 pseudo-random number generators.
195 * VMClass and the reference implementations of Method, Constructor and Field
196 now include a number of 1.5 methods imported from the generics branch.
197 These are all optional (in the sense that the methods associated with them
198 merely fail on use if the VM doesn't provide them, rather than the
199 VM failing altogether), but VMs should aim to support them where possible.
200 * The implementation of java.lang.instrument has been merged to the main
201 branch from the generics branch.
202 * The VM interfaces of the main branch and the generics branch are now
203 consistent with one another. As a result, the main branch includes an
204 additional environ() function in VMSystem and an additional argument has
205 been added to nativeSpawn() in VMProcess.
206 * Annotation support is now available in the main branch, if the VM supports
207 it. The VM should implement VMClass.getDeclaredAnnotations,
208 Constructor.getAnnotation, Constructor.getDeclaredAnnotations,
209 Field.getAnnotation, Field.getDeclaredAnnotations, Method.getAnnotation and
210 Method.getDeclaredAnnotations.
211 * java.lang.Package now has a new constructor that takes the defining
212 ClassLoader as an extra argument. If you use a custom version of
213 VMClassLoader, please switch it to use this constructor.
214 * The reference implementation of VMClassLoader.getBootPackages() now
215 reads the META-INF/INDEX.LIST resource using the java.boot.class.path
216 system property.
217
218 New in release 0.90 (March 6, 2006)
219
220 * Free Swing improvements: JTable columns are rearrangeable and
221 resizeable with mouse. Painting and scrolling are now much
222 faster. Plain text components now support highlighting and
223 copy+paste to the system clipboard. Support for styled text has been
224 improved, including some very basic HTML support. JFileChooser is
225 now usable. Global event dispatching has been implemented. Memory
226 consumption of Swing components has been reduced. Lots of general
227 bugfixes. Added new system property to turn off Graphics2D use in
228 Swing, even if Graphics2D is available: gnu.javax.swing.noGraphics2D
229
230 * AWT. Improved support for mixing "lightweight" and "heavyweight"
231 Components in Containers. Better support for dynamically updated
232 menus. Better 1.0 event model support for Scrollbars. Better class
233 documentation of gtk+ awt peers.
234
235 * GNU Crypto and Jessie have been merged into GNU Classpath; this
236 provides Classpath with a wide array of cryptographic algorithms
237 (ciphers, message digests, etc.) and implementations of SSL version
238 3 and TLS version 1. These roughly complement the public
239 `java.security.' `javax.crypto,' and `javax.net.ssl' packages, and
240 are service providers implementing the underlying algorithms.
241
242 * Updated HTTP and FTP URLConnection protocol handlers. HTTPS support
243 out of the box.
244
245 * Unicode 4.0.0 is supported. Character now includes support for using
246 ether a char or an int to identify code points.
247
248 * More correct handling of Object methods and serialization support
249 for Proxy and abstract classes.
250
251 * The new folder tools includes GIOP and RMI stub and tie source code
252 generators, IOR parser and both transient and persistent GIOP naming
253 services.
254
255 * Added experimental support for dynamic creation of the RMI stubs
256 using proxy classes. The rmic compiler is no longer required (unless
257 for research and specific stubs).
258
259 * XML validaton support for RELAX NG and W3C XML schema namespace
260 URIs. RELAX NG pluggable XML schema datatype library API and an
261 implementation for XML Schema Datatypes
262 (http://www.w3.org/TR/xmlschema-2/).
263
264 * Updated StAX implementaton to be compatible with final JSWDP 2.0.
265
266 * The default back end for java.util.prefs has been changed. The new
267 default is capable of saving and restoring preferences to and from
268 the file system.
269
270 * javax.imageio.plugins.bmp implementation.
271
272 * Added --enable-collections configure option which builds
273 "collections.jar", a 1.1 VM compatibility jar.
274
275 * gnu.regexp updated from GNU/Posix syntax to support util.regex
276 syntax including various Unicode blocks, categories and properties.
277
278 Runtime interface changes:
279
280 * A new class, VMMath, is now available which separates the native
281 mathematical functions from java.lang.Math. The previous fdlibm
282 implementation now forms the reference material for this class.
283
284 * Updated VMObjectInputStream class to return Thread context class
285 loader if no other class loader is found.
286
287 * Updated documentation on InstrumentationImpl in vmintegration guide.
288
289 New in release 0.20 (Jan 13, 2006)
290
291 * New StAX pull parser and SAX-over-StAX driver. Lots of DOM, SAX/StAX,
292 XPath and XSLT improvements. Support for XInclude and XML Base added.
293 Conformance is now regularly tested against various test-suites at
294 http://builder.classpath.org/xml/ See also doc/README.jaxp.
295
296 * Full beans XMLEncoder implementation.
297
298 * javax.sound.sampled implementation.
299
300 * javax.print.attribute and javax.print.event implementated.
301
302 * Lots of new datatransfer, print swing and swing.text work and optimization.
303
304 * Additional 1.5 support. Including new (separate) generic branch release.
305
306 * SecurityManager cleanups and start of review of all Permission checks
307 (includes adding lots of new checks to the Mauve test-suite).
308
309 * Buildable on cygwin.
310
311 * Fully buildable as "in-workspace" library-plus-vm inside (native) Eclipse
312 see http://developer.classpath.org/mediation/ClasspathHackingWithEclipse
313
314 * Full example that shows a real world CORBA and Free Swing implementation.
315 See examples/gnu/classpath/examples/CORBA/swing/README.html
316
317 * A list of bug fixes can be found at:
318 http://gcc.gnu.org/bugzilla/buglist.cgi?product=classpath&target_milestone=0.20
319
320 Runtime interface changes:
321
322 * New method VMStackWalker.getClassLoader() was added to avoid an infinite
323 loop between getCallingClassLoader() and Class.getClassLoader().
324
325 * The included fdlibm implementation has seen several cleanups to handle
326 new architectures and namespacing issues (in particular for ppc, darwin
327 and non-C99 compilers). Please double check any arithmetic test against
328 new platforms/runtimes.
329
330 * The gnu.java.net.Plain[Datagram]Socket implementations have been
331 turned into VM reference classes with JNI/Posix implementations.
332
333 New in release 0.19 (Nov 2, 2005)
334
335 * The Swing RepaintManager has been reworked for more efficient painting,
336 especially for large GUIs.
337
338 * The Swing layout manager OverlayLayout has been implemented, the BoxLayout
339 has been rewritten to make use of the SizeRequirements utility class and
340 caching for more efficient layout.
341
342 * Improved accessibility support for Swing.
343
344 * The java.net.HttpURLConnection implementation no longer buffers the
345 entire response body in memory. This means that response bodies
346 larger than available memory can now be handled.
347
348 * The Andrew Watson, Vice President and Technical Director of the Object
349 Management Group, has officially assigned us 20 bit Vendor Minor Code Id:
350 0x47430 ("GC") that will mark remote Classpath - specific system exceptions.
351 Obtaining the VMCID means that GNU Classpath now is a recogniseable type of
352 node in a highly interoperable CORBA world.
353
354 * Classpath now includes the first working draft to support the RMI over
355 IIOP protocol. The current implementation is capable for remote invocations,
356 transferring various Serializables and Externalizables via RMI-IIOP protocol.
357 It can flatten graphs and, at least for the simple cases, is interoperable
358 with Sun's jdk 1.5.
359
360 * Qt4 configury switches for OS-X. Additional to the --enable-qt-peer, OS-X
361 users with a Qt4 installation can build the qt-peers with the argument
362 --with-qt4dir=<Qt4-installation-dir>.
363
364 * Significant progress has been made in the implementation of the
365 javax.swing.plaf.metal.* package, with most UI delegates in a working state
366 now. Please test this with your own applications and provide feedback that
367 will help us to improve this package.
368
369 * The GUI demo (gnu.classpath.examples.swing.Demo) has been extended to
370 highlight various features in our free-swing implementation. And includes
371 a look and feel switcher (Metal default, Ocean or GNU).
372
373 Runtime interface changes:
374
375 * Changed implementation of VMClassLoader.getPackage(s) : new method
376 VMClassLoader.getBootPackages should be implemented by the vm, and sould
377 return a string array of boot package names ("java.lang", "java.net", ...).
378 Feedback from vm implementors for usability and relevance of the
379 getBootPackages method would be greatly appreciated.
380
381 New in release 0.18 (Sep 6, 2005)
382
383 * GNU JAWT implementation, the AWT Native Interface, which allows direct
384 access to native screen resources from within a Canvas's paint method.
385 GNU Classpath Examples comes with a Demo, see examples/README.
386 * awt.datatransfer updated to 1.5 with supports for FlavorEvents.
387 The gtk+ awt peers now allow copy/paste of text, images, uris/files
388 and serialized objects with other applications and tracking
389 clipboard change events with gtk+ 2.6 (for gtk+ 2.4 only text and
390 serialized objects are supported). A GNU Classpath Examples
391 datatransfer Demo was added to show the new functionality.
392 * org.omg.PortableInterceptor and related functionality in other packages
393 is now implemented:
394 - The sever and client interceptors work as required since 1.4.
395 - The IOR interceptor works as needed for 1.5.
396 * The org.omg.DynamicAny package is completed and passes the prepared tests.
397 * The Portable Object Adapter should now support the output of the
398 recent IDL to java compilers. These compilers now generate servants and
399 not CORBA objects as before, making the output depended on the existing
400 POA implementation. Completing POA means that such code can already be
401 tried to run on Classpath. Our POA is tested for the following usager
402 scenarios:
403 - POA converts servant to the CORBA object.
404 - Servant provides to the CORBA object.
405 - POA activates new CORBA object with the given Object Id (byte array)
406 that is later accessible for the servant.
407 - During the first call, the ServantActivator provides servant for this
408 and all subsequent calls on the current object.
409 - During each call, the ServantLocator provides servant for this call
410 only.
411 - ServantLocator or ServantActivator forwards call to another server.
412 - POA has a single servant, responsible for all objects.
413 - POA has a default servant, but some objects are explicitly connected
414 to they specific servants.
415 The POA is verified using tests from the former cost.omg.org.
416 * The javax.swing.plaf.multi.* package is now implemented.
417 * Editing and several key actions for JTree and JTable were implemented.
418 * Lots of icons and look and feel improvements for Free Swing basic and
419 metal themes were added. Try running the GNU Classpath Swing Demo in
420 examples (gnu.classpath.examples.swing.Demo) with:
421 -Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel
422 -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel
423 * Start of styled text capabilites for java.swing.text.
424 * NIO FileChannel.map implementation, fast bulk put implementation for
425 DirectByteBuffer (speeds up this method 10x).
426 * Split gtk+ awt peers event handling in two threads and improve gdk lock
427 handling (solves several AWT lock ups).
428 * Speed up awt Image loading.
429 * Updated TimeZone data against Olson tzdata2005l.
430 * Make zip and jar UTF-8 "clean".
431 * "native" code builds and compiles (warning free) on Darwin and Solaris.
432
433 Runtime interface changes:
434
435 * All native resource "pointers" in the VM interface classes are now exposed
436 as gnu.classpath.Pointer objects. This might impact runtimes that
437 optimize and support java.nio.DirectByteBuffers. Creating these classes
438 and accessing the contents as void * pointers for the native reference JNI
439 implementation is done through the JCL_NewRawDataObject and JCL_GetRawData
440 functions.
441 * Simplified the Class/VMClass interface.
442 * Removed loadedClasses map from ClassLoader. It's now the VMs responsibility
443 to manage the list of defined and loaded classes for each class loader.
444 * Moved native methods from java.lang.reflect.Proxy to VMProxy.
445 * Added hook to VMClassLoader to allow VM to do class caching.
446
447 New Untested/Disabled Features:
448
449 The following new features are included, but not ready for production
450 yet. They are explicitly disabled and not supported. But if you want
451 to help with the development of these new features we are interested
452 in feedback. You will have to explicitly enable them to try them out
453 (and they will most likely contain bugs). If you are interested in any
454 of these then please join the mailing-list and follow development in
455 CVS.
456
457 * QT4 AWT peers, enable by giving configure --enable-qt-peer.
458 * JDWP framework, enable by deleting the jdwp references from
459 lib/standard.omit and vm/reference/standard.omit. No default
460 implementation is provided. Work is being done on gcj/gij integration.
461 * StAX java.xml.stream, enable by deleting the gnu.xml.stream and
462 java.xml.stream references in lib/standard.omit.
463
464 New in release 0.17 (Jul 15, 2005)
465
466 * gnu.xml fix for nodes created outside a namespace context.
467 * Add support for output indenting and cdata-section-elements output
468 instruction in xml.transform.
469 * xml.xpath corrections for cases where elements/attributes might have
470 been created in non-namespace-aware mode. Corrections to handling of
471 XSL variables and minor conformance updates.
472 * DefaultMutableTreeNode preorder, postorder, depthFirst and breadthFirst
473 traversal enumerations implemented.
474 * JInternalFrame colors and titlebar draw properly.
475 * JTree is working up to par (icons, selection and keyboard traversal).
476 * JMenus were made more compatible in visual and programmatic behavior.
477 * JTable changeSelection and multiple selections implemented.
478 * JButton and JToggleButton change states work properly now.
479 * JFileChooser fixes.
480 * revalidate and repaint fixes which make Free Swing much more responsive.
481 * Correctly handle system call interrupts and timeouts in native nio
482 and net functions.
483 * MetalIconFactory implemented.
484 * Handle image loading errors correctly for gdkpixbuf and MediaTracker.
485 * Added Tree World to GNU Classpath examples Free Swing demo.
486 * FileChannel.lock() and FileChannel.force() implemented.
487 * java.util.logging.FileHandler now rotates files.
488 * Better handle GDK lock. Properly prefix gtkpeer native functions (cp_gtk).
489 * Corba bug fixes and documentation updates.
490 * Updated gcj build infrastructure.
491 * Documentation fixes all over the place.
492 See http://developer.classpath.org/doc/
493 * VM Integration Guide updates with a full section on VM/Classpath hooks.
494
495 New in release 0.16 (Jun 30, 2005)
496
497 * Better GTK scrollbar peer implementation when using GTK >= 2.6.
498 * GdkGraphics2D has been updated to use Cairo 0.5.x APIs.
499 * BufferedImage and GtkImage rewrites. All image drawing operations
500 should now work correctly (flipping requires gtk+ >= 2.6)
501 * Future Graphics2D, Image and Text work is documented at:
502 http://developer.classpath.org/mediation/ClasspathGraphicsImagesText
503 * Free Swing Top-Level Compatibility. JFrame, JDialog, JApplet,
504 JInternalFrame, and JWindow are now 1.5 compatible in the sense that you
505 can call add() and setLayout() directly on them, which will have the same
506 effect as calling getContentPane().add() and getContentPane().setLayout().
507 * The JTree interface has been completed. JTrees now recognizes mouse clicks
508 and selections work, but the visual implementation is not yet complete.
509 Work on expansion and collapsing of the tree nodes is being implemented.
510 * BoxLayout works properly now.
511 * Fixed GrayFilter to actually work.
512 * Metal SplitPane implemented.
513 * Lots of free swing text and editor stuff work now.
514
515 * When gtk+ 2.6 or higher is installed the default log handler will produce
516 stack traces whenever a WARNING, CRITICAL or ERROR message is produced.
517
518 * The CORBA implementation is now a working prototype that should support
519 features up till 1.3 inclusive.
520 We would invite groups writing CORBA dependent applications to
521 try Classpath implementation, reporting any possible bugs.
522
523 The CORBA prototype is interoperable with Sun's implementation v 1.4,
524 transferring object references, primitive types, narrow and wide
525 strings, arrays, structures, trees, abstract interfaces and
526 value types (feature of CORBA 2.3) between these two platforms.
527 The remote exceptions are transferred and handled correctly.
528 The stringified object references (IORs) from various sources are
529 parsed as required.
530 The transient (for current session) and permanent (till jre restart)
531 redirections work.
532 Both Little and Big Endian encoded messages are accepted.
533 The implementation is verified using tests from the former cost.omg.org.
534 The current release includes working examples (see the examples directory),
535 demonstrating the client-server communication, using either CORBA Request
536 or IDL-based stub (usually generated by a IDL to java compiler).
537 These examples also show how to use the Classpath CORBA naming service.
538 The IDL to java compiler is not yet written, but as our library must be
539 compatible, it naturally accepts the output of other idlj implementations.
540
541 * New --with-vm-classes configure option, and new 'build' setting
542 for --with-glibj. (Only for integrators.)
543
544 Runtime interface changes:
545
546 * Start of a generic JDWP framework in gnu/classpath/jdwp.
547 This is unfinished, but feedback (at classpath@gnu.org) from runtime
548 hackers is greatly appreciated. Although most of the work is currently
549 being done around gcj/gij we want this framework to be as VM neutral as
550 possible. Early design is described in:
551 http://gcc.gnu.org/ml/java/2005-05/msg00260.html
552 * Native method VMClass.getModifiers() now takes an additional
553 boolean parameter.
554 * Deprecated native method VMClassLoader.defineClass(ClassLoader,
555 String, byte[], int, int) has been replaced by
556 VMClassLoader.defineClass(ClassLoader, String, byte[], int, int,
557 ProtectionDomain)
558 * VMClassLoader.loadClass(String name, boolean resolve) is now native,
559 replacing the former version which just returned null.
560 * Deprecated native method VMClassLoader.getPrimitiveClass(String) has
561 been replaced by new native method VMClassLoader.getPrimitiveClass(char).
562 * Previously empty implementations of methods VMThread.countStackFrames(),
563 VMThrowable.fillInStackTrace(), and VMThrowable.getStackTrace() have
564 been removed; these methods are now native methods.
565 * Fields "exceptionTypes" and "parameterTypes" have been removed from
566 Contructor.java and getExceptionTypes() and getParameterTypes() are
567 now native methods.
568
569 New in release 0.15 (Apr 29, 2005)
570
571 * The old character encoding framework (gnu.java.io.EncodingManager)
572 has been replaced by a system based completely on nio.charset
573 providers. Many converters have been added, both the io, lang and nio
574 frameworks now use the same set of converters and the whole character
575 stream framework (Readers and Writers) have been optimized. For some
576 workloads this leads to 2x till 20x speedups.
577
578 The default charsets supported are:
579
580 Cp424, Cp437, Cp737, Cp775, Cp850, Cp852, Cp855, Cp857, Cp860, Cp861,
581 Cp862, Cp863, Cp864, Cp865, Cp866, Cp869, Cp874, ISO_8859_1, ISO_8859_13,
582 ISO_8859_15, ISO_8859_2, ISO_8859_3, ISO_8859_4, ISO_8859_5, ISO_8859_6,
583 ISO_8859_7, ISO_8859_8, ISO_8859_9, KOI_8, MS874, MacCentralEurope,
584 MacCroatian, MacCyrillic, MacDingbat, MacGreek, MacIceland, MacRoman,
585 MacRomania, MacSymbol, MacThai, MacTurkish, US_ASCII, UTF_16, UTF_16BE,
586 UTF_16Decoder, UTF_16Encoder, UTF_16LE, UTF_8, UnicodeLittle, Windows1250,
587 Windows1251, Windows1252, Windows1253, Windows1254, Windows1255,
588 Windows1256, Windows1257, Windows1258.
589
590 Many more encoding are supported through the new IconvProvider
591 depending on the platform iconv support. GNU libiconv is recommended.
592 The IconvProvider is currently not enabled by default. To enable it
593 define the system property gnu.classpath.nio.charset.provider.iconv=true.
594 Some runtimes might choose to enable this by default by setting it
595 through VMSystemProperties. We would like to get feedback on whether
596 enabling or disabling the IconvProvider by default results in the
597 highest speedups.
598
599 * Free swing metal and pluggable look and feels have been improved.
600 The GNU Classpath free swing example can now be run with different
601 "skins" by setting the system property swing.defaultlaf to the GNU,
602 Basic or Metal look and feel.
603
604 * Some of the org.omg.CORBA classes and packages have now been
605 implemented. The Savannah bug tracker contains additional tasks for
606 which we are seeking help.
607
608 * Fixed compatibility problems in the java.beans which affected
609 Eclipse's Visual Editor Project.
610
611 * New completely lock free (Inheritable)ThreadLocal implementation.
612
613 * javax.swing.text.rtf framework added which can handle simple (plain)
614 text tokens.
615
616 * Support for parsing html files into Level 2 Document Object Model
617 (org.w3c.dom.html2 and javax.swing.text.html.parser). And a start of
618 javax.swing.text.html framework added.
619
620 Runtime interface changes:
621
622 * jni.h changed to better support compiling runtimes implementing jni;
623 see VM integration guide for details.
624 * New --enable-default-toolkit option to configure can be used to set
625 the fully qualified class name of the default AWT toolkit to use.
626 If not given, the old default of gnu.java.awt.peerk.gtk.GtkToolkit
627 is used.
628 * New --disable-core-jni option can be used to disable building the
629 "core" JNI libraries. This is primarily useful if your VM can use the
630 Gtk peers but not the core JNI libraries.
631 * New system property "gnu.classpath.boot.library.path" can be specified
632 to define the location of the JNI libraries. It is by all means meant
633 ONLY for VM implementors and GNU Classpath hackers. See the hacking
634 guide for more information.
635 * The helper methods currentLoader() and allocateObject() for
636 java.io.ObjectInputStream have been moved to a VMObjectInputStream class.
637 Reference implementations are provided.
638 * java.net.InetAddress now uses VMInetAddress for runtime/platform
639 specific methods getLocalHostname(), getHostByAddr() and
640 getHostByName(). java.net.NetworkInterface now uses VMNetworkInterface
641 for runtime/platform specific getInterfaces() support. Default
642 (Posix/GNU JNI) implementations are provided.
643 * VMClass has a new method getModifiers(Class, boolean) which can be
644 used to get the real modifiers for an inner class or the ones
645 specified by the InnerClasses attribute.
646 * All (possible) runtime specific methods of Object and Double are now
647 in VMObject and VMDouble. Where possible generic reference
648 implementations are provided.
649 * The reference implementation of VMClassLoader now handles zip files
650 on the boot loader class path in getResources().
651
652 Other changes:
653
654 New in release 0.14 (Feb 25, 2005)
655
656 * Character encoders and decoders have been added for:
657 iso-8859-6 (arabic), iso-8859-7 (greek), iso-8859-8 (hebrew),
658 iso-8859-9 (latin-5), iso-8859-13, iso-8859-15 (latin-9), cp1047 (ebcdic),
659 ebcdic-xml-us,ascii, windows-1250, windows-1252, UTF-16BE (Big Endian),
660 UTF-16LE (Little Endian), UTF-32BE (Big Endian), UTF-32LE (Little Endian).
661 * Full documentation for all classes can be generated (again) by using
662 the --with-gjdoc configure option.
663 * javax.awt.imageio support through gdkpixbuf.
664
665 Runtime interface changes:
666
667 * VMSecurityManager has been replaced by gnu.classpath.VMStackWalker.
668 currentClassLoader() is no longer needed, and there are also two new
669 methods with non-native implementations. VM implementors are encouraged
670 to provide more efficient versions.
671 * VMRuntime.nativeLoad() now takes an additional ClassLoader parameter.
672
673 New in release 0.13 (Jan 6, 2005)
674
675 * The http url protocol handler has been replaced with a full HTTP/1.1
676 version from GNU inetlib.
677 * A new ftp url protocol handler has been added also from GNU inetlib.
678 * java.beans has been updated to 1.4 including support for XMLEncoder
679 and XMLDecoder.
680 * The java.util.Locale support is now based on the Common Locale Data
681 Repository (CLDR) Project (see http://www.unicode.org/cldr/).
682 GNU Classpath provides support for more than 250 locales now.
683 This new support is experimental and the GNU Classpath hackers are
684 working together with runtime developers and the unicode consortium
685 to improve them in the future.
686 If your runtime misdetects your locale or if the default locale gives
687 problems please try running with -Duser.language=en and -Duser.region=US
688 to fall back on a known good locale.
689 * Added implementations of javax.xml (JAXP 1.3), org.xml.sax (SAX2) and
690 org.w3c.dom (DOM Level 3) interfaces. It is possible to switch between
691 different implementations AElfred2, GNU DOM, GNU XSL, libxmlj SAX,
692 libxmlj DOM and libxmlj XSL by setting different system properties.
693 Also provided is a preliminary XPath 1.0 implementation.
694 The libxmlj versions are build around libxml2 and libxslt and have to
695 be enabled during build time by the --enable-xmlj configure flag.
696 The current support is equal to the last released GNU JAXP 1.3 release.
697 These packages will be maintained as part of the GNU Classpath core classes
698 in the future. For more information, conformance results and documentation
699 on selecting different implementations see doc/README.jaxp.
700 * More AWT accessible support.
701 * AWT gtk+ peers component layout, dialog placement, keyboard focus
702 handling and text positioning have been improved.
703 * ImageIO interfaces are more complete.
704 * JList, JTable and JTree have been hugely improved.
705 * java.awt.Robot support with GdkRobot in the gtk+ awt peers.
706 Needs XTest Extension (libXtst) XServer support.
707 * New --disable-examples configure argument.
708
709 Runtime interface changes:
710
711 * Added a new method (VMRuntime.enableShutdownHooks) that enables the VM
712 to lazily register an exit handler.
713 * The java.lang.Class constructor now automatically sets the protection
714 domain for array classes, based on the protection domain of the component
715 type class.
716 * New gnu.classpath.VMSystemProperties class. This replaces the
717 system properties initialization in VMRuntime. Note that it is
718 now the VMs responsibility to set one additional property:
719 gnu.cpu.endian should be set to "big" or "little".
720 * VMRuntime.nativeGetLibname() has been renamed to VMRuntime.mapLibraryName()
721 and has only one argument, the name of the library.
722 * String and StringBuffer now call VMSystem.arraycopy() directly and don't
723 go through java.lang.System. Be careful to not initialize java.lang.System
724 early in the bootstrap sequence in your VM runtime interface classes.
725 * Some (wrong) documentation about the behavior of VMThread.sleep(0, 0)
726 has been updated. Also, VMThread.sleep() now has a default non-native
727 implementation, but it is a generic implementation that ignores the
728 nano-seconds argument. Runtime hackers are encouraged to provide a more
729 efficient version.
730 * There is prelimenary support for nio direct byte buffers.
731 See VMDirectByteBuffer. Please contact the GNU Classpath mailinglist when
732 you add support for this to your runtime.
733
734 New in release 0.12 (Nov 14, 2004)
735
736 * GNU Classpath's JAR implementation now has preliminary support for
737 signed entries, for so called "signed JAR" file support. Signed JAR
738 files are one of the key security features of managed runtimes, and
739 allows code to run privileged given unforgeable proofs of identity.
740 * A much improved version of X.509 certificates has been added,
741 including a robust certificate path checking algorithm. Also
742 included is an implementation of the RSA signature scheme.
743 * Full java.awt.color implementation, with all standard ICC profiles,
744 except for PhotoYCC color space.
745 * java.beans 1.4 updates and bug fixes.
746 * java.awt.image support updated to 1.4.
747 * Improved build process. Uses less memory with gcj and C code is
748 buildable with -Werror on most platform. Please configure with
749 --enable-Werror and report any remaining issues.
750 * Big-endian (PowerPC) fixes for native awt GTK+ peers.
751 * Checkstyle support, see scripts/checkstyle-config.xml.
752 * Better AWT focus management fro GTK+ peers.
753 * Much faster and better fonts support
754 (for both gdk Graphics and cairo Graphics2D)
755 * AWT Choice fixes for hidden components.
756 * HTTP Connection Handler fixes for POST support.
757 * Much fuller collection documentation.
758 * Lots of Calendar bug fixes.
759 * More javax.imageio support.
760 * Better AWT Help MenuBar support.
761 * Lookahead support for regular expressions.
762 * Serialization object stream fixes for multiple ClassLoader scenarios.
763 * Swing TabbedPane, ColorChooser and ComboBox improvements.
764 * Start of JTree functionality.
765 * Improved Eclipse 3 support for GNU Classpath based runtimes.
766
767 Runtime interface Changes:
768
769 * New --enable-java-lang-system-explicit-initialization configuration
770 option. (Warning, will be replaced in next release, please consult
771 the mailinglist.)
772 * The reference implementation of VMClassLoader has default
773 implementations for getResource(s) and provides support for a new
774 default getSystemClassLoader implementation.
775
776 New in release 0.11 (Sep 13, 2004)
777
778 * javax.swing.Spring and SpringLayout support.
779 * Added pluggable look and feel support for BasicTextFieldUI and
780 BasicToolBarSeparatorUI.
781 * java.swing.text support for (Default and Layered) Highlighter, FieldView,
782 PlainView, TabExpander and TabableView added.
783 * Start of JTable and JTree implementation.
784 * Internal Swing frames work.
785 * JMenu and JPopupMenu work.
786 * New gtk+ AWT FileDialog peer now based on gtk+2.4 or higher.
787 * java.awt.image LookupTables and kernel support.
788 * Improved java.awt.image.BufferedImage support.
789 * AWT 1.0 event model support.
790 * GNU Classpath now comes with some example programs (see examples/README).
791 * New javax.crypto, javax.crypto.interfaces, javax.crypto.spec, javax.net,
792 javax.net.ssl, javax.security.auth, javax.security.auth.callback,
793 javax.security.auth.login, javax.security.auth.x500, javax.security.sasl
794 and org.ietf.jgss packages are now officially part of GNU Classpath.
795 Extra crypto algorithms can be obtained from the GNU Crypto project,
796 a full TLS implementation is provided by the Jessie project.
797 http://www.gnu.org/software/gnu-crypto/
798 http://www.nongnu.org/jessie/
799 * Frame.setIconImage() support.
800 * AWT GDKGraphics scaling.
801 * New configure flag --enable-gtk-cairo to build Graphics2D implementation
802 build on cairo and pangoft2. Enabled at runtime by defining the system
803 property gnu.java.awt.peer.gtk.Graphics=Graphics2D.
804 * javax.swing.JSpinner implemented.
805 * Extensive documentation update for java.util collection classes.
806 * java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented.
807 * GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and
808 tool integrators are encouraged to directly integrate GNU JAXP.
809 This release has been tested against GNU JAXP 1.1.
810 http://www.gnu.org/software/classpathx/jaxp/jaxp.html
811 * JColorChooser, JComboBox and JTextField implemented, including example
812 uses in GNU Classpath Examples swing Demo.
813
814 Runtime interface Changes:
815
816 * java.lang.Compiler now uses the new java.lang.VMCompiler; there is
817 a reference implementation that most VMs can use.
818 * java.lang.VMSystem has a new getenv(String) method and a reference C/JNI
819 implementation that should work on most Posix like systems.
820 * java.util.TimeZone has been split into a platform independent class and
821 a platform dependent class VMTimeZone. GNU Classpath comes with a generic
822 way to get at the default time zone for Posix/GNU-like platforms.
823 * [VM]AccessController improvements. In particular it handles
824 `doPrivileged' calls better, and allows for recursive `doPrivileged'
825 calls in the same Thread. (see vm/reference/java/security/)
826
827 New in release 0.10 (Jul 9, 2004)
828
829 * java.net.URL now uses application classloader to load URLStreamHandlers
830 and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
831 * java.io.File.deleteOnExit() implementation.
832 * java.text multiple new features and bug fixes
833 (only 2 out of the 1000+ java.text Mauve tests now fail).
834 * Better (non-black) default AWT System colors.
835 * AWT lists use GTK treeviews.
836 * Proper AWT focus management has been implemented.
837 * Swing menus and scrollpanes are beginning to work.
838 * Swing splitpanes, dialogs and internal frames were added.
839 * Swing repainting / double buffering was redone.
840 * Font management and Pango DPI conversion fixes.
841 * A lot of AWT imaging and event bugs have been picked out.
842 * More of javax.swing.text has been implemented.
843 * javax.swing.Timer has been reimplemented.
844 * java.security.AccessController has been implemented
845 (see runtime section).
846 * The default java.lang.SecurityManager now uses AccessController.
847 * New java.beans.Statement and Expression implementations.
848 * Small FileChannel implementation speed improvement for traditional
849 JNI based systems.
850 * Regenerated all included JNI header files with gcjh (3.5 CVS),
851 removes extra extern modifier and allows stricter compiler warning.
852 * More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
853 -Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
854 made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
855 * Double.toString() and Float.toString() now work properly on 64-bit
856 PowerPC systems.
857 * PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
858 * Build system refactored and removed old Japhar specific support.
859 * The gnu.java.awt.EmbeddedWindow class has been improved, and now
860 supports embedding AWT windows in other top-level X windows.
861 This functionality is required by gcjwebplugin.
862 * gcjwebplugin, an applet viewer that can be embedded into several web
863 browsers, has been extensively tested with this release of classpath.
864 (See http://www.nongnu.org/gcjwebplugin/)
865 * Runtime environments based on GNU Classpath 0.10 should be able to
866 start up Eclipse 3.0 out of the box now.
867
868 Runtime interface Changes:
869
870 * VMProcess.destroy() default implementation fixes.
871 * Fixed the "portable native sync" code; it had been broken since
872 Classpath release 0.06, when we upgraded to GTK+2.
873 Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses
874 the platform's native threading model -- pthreads in most cases.
875 If the Java runtime doesn't use the native threading model, then you should
876 specify --portable-native-sync when configuring Classpath, so that GLIB will
877 use the Java threading primitives instead. (For a superior alternative,
878 see below.)
879 * The VM can set the system property
880 gnu.classpath.awt.gtk.portable.native.sync instead of using the
881 --portable-native-sync configure-type option.
882 See doc/vmintegration.texinfo for details.
883 * We intend that the next release of GNU Classpath will require the VM
884 to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for
885 one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
886 If this poses problems, please raise them on the classpath mailing list.
887 * The reference implementation of VMThread.holdsLock(Object) now has
888 a default implementation written in java. For efficiency and to
889 prevent spurious wakeups a real 'native' runtime version can be supplied.
890 * There is a new java.security.VMAccessController class that runtimes need
891 to implement to properly support SecurityManagers. The default
892 implementation that comes with GNU Classpath makes sure that ANY attempt
893 to access a protected resource is denied when a SecurityManager is
894 installed. Which is pretty secure, but also no very useful.
895 Please see the documentation in
896 vm/reference/java/security/VMAccessController.java,
897 and please give feedback on the GNU Classpath mailinglist whether or not
898 the current AccessController framework is flexible enough.
899
900 New in release 0.09 (May 2, 2004)
901
902 * Includes updated GNU JAXP version from 2004-02-01.
903 * Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean.
904 * java.io is now implemented by delegating most tasks directly to java.nio.
905 * Reworked/Optimized implementations of java.nio.Buffer and subclasses.
906 * New javax.print, javax.print.attribute[.standard] and javax.print.event
907 packages and classes.
908 * java.text attributed iterators support.
909 * New javax.imageio, javax.imageio.event and javax.imageio.spi packages and
910 classes.
911 * GNU Classpath can now load service providers that are described via
912 META-INF/services/* resources in extension JARs. This is useful for
913 implementing the various APIs that are supposed to be extensible via
914 custom plugins. For details, please see the documentation of
915 gnu.classpath.ServiceFactory.
916 Application developers are strongly discouraged from calling glibj
917 internal packages. Instead, they might want invoke the newly implemented
918 javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard
919 method for loading plug-ins.
920 * New developers wanting to help the GNU Classpath project might want to
921 review the greatly expanded Hacker Guide included in the doc directory
922 or online at http://www.gnu.org/software/classpath/docs/hacking.html
923 Also the FAQ has been expanded. And when working from CVS you can now use
924 a simple autogen.sh script to get all autotools magic done automagically.
925 * New configure option --with-glibj which defines how to install the glibj
926 class files as zip, as flat directory files or both (zip|flat|both)
927 [default=zip]. When working with multiple runtimes some of which might
928 not support bootstrap classes in zip files the --with-glibj=both option
929 is recommended (this does take extra disc space).
930 * Two big code drops from the libgcj gui branch updating various java.awt
931 and javax.swing classes.
932 * Multiple java.net.InetAdress fixes and java.rmi fixes.
933 * ServerSocket.accept() now restarts listening when system call interrupted.
934 * Much cleanups to make standard API doc valid XHTML (not completed yet).
935 * A scan for unused variables and non-static invocation of static methods
936 turned up a couple of subtle bugs which have now all been fixed.
937 * The Mauve testsuite has been cleaned up considerable and lots of issues
938 in the GNU Classpath core class implementation have been fixed.
939
940 VM Interface changes:
941
942 * java.lang.Class/VMClass interface was changed. The interface now no
943 longer requires an instance of VMClass for each Class instance. Instead
944 the field vmdata in Class is now of type Object.
945 * GNU Classpath now assumes that JNI calls SetXField can modify final
946 fields. This was previously used silently for System.in/out/err and should
947 be considered as a feature now.
948 * A new VMProcess and a sample JNI C implementation are now provided to
949 make Runtime.exec() work out of the box on some systems. This requires
950 a small change to VMRuntime.exec() when a runtime wants to use it as the
951 default java.lang.Process implementation.
952 * The implementation of most of java.io through java.nio moved serveral
953 runtime specific I/O methods. Most methods do have a generic default native
954 C JNI implementation in native/jni/java-nio.
955 * Runtime support methods for java.io.File have been moved to VMFile which
956 also comes with a default JNI C implementation.
957 * To support the new service provider mechanism runtimes must make sure that
958 extension JARs are made accessible via the default context class loader.
959
960 New in release 0.08 (2004/12/03)
961
962 * java.util.regexp implementation through gnu.regexp wrappers.
963 * java.net.URI implementation.
964 * Working implementation of javax.swing.undo.
965 * java.awt.geom.CubicCurve2D/QuadCurve2D: Can now solve cubic and quadratic
966 equations; implementation adapted from the GNU Scientific Library.
967 * Lots of java.awt and gtk+ peer improvements. Also more Swing work. Start
968 of EmbeddedWindow support.
969 * BufferedReader speed improvements.
970 * Improved useabilty of java.text implementation for several applications.
971 * ObjectInputStream is much faster and more compatible with other
972 implementations.
973 * Fix handling of alias methods, where a method has been deprecated in
974 favour of a new one with the same funtion but a different name.
975 (See Deprecated Methods section in the GNU Classpath Hacking Guide.)
976 * javax.print.attribute.standard added.
977 * Lots of java.nio, java.net, java.io
978 * Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+.
979
980 VM Interface changes:
981 * Split native methods in java.lang.Runtime into java.lang.VMRuntime.
982 * Resources are now also loaded/needed through the bootstrap classloader
983 (gnu.regexp needs MessageBundle included in glibj.zip
984
985 Fixed Classpath bugs:
986 #6095 java.awt.geom.QuadCurve2D.solveQuadratic sometimes gives
987 wrong results
988 #7099 EventListenerList.getListenerCount should accept null argument
989 #7104 EventListenerList.add does not work
990 #7105 EventListenerList.remove does not work
991 #7107 DefaultBoundedRangeModel.setValue and friends should not throw
992 And lots more.
993
994 New in release 0.07 (2003/30/11)
995
996 * Works with libtool 1.5 (and 1.4.3).
997 * java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango.
998 Lots and lots improvements on the peers.
999 * java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D:
1000 Subdivision and flatness calculation implemented.
1001 * java.awt.geom.FlatteningPathIterator: Working implementation.
1002 * gnu.java.awt.BitwiseXORComposite helper class.
1003 * New rmic compilers (jikes, kjc) support.
1004 * java.text bug fixing and 1.4 updates (Currency).
1005 * Hashtable and HashMap function more similar to other implementations.
1006 * javax.naming and java.beans classloader fixes.
1007 * URL parsing, URLConnection, protocol and (needed) permission fixes.
1008 * More java.nio implementation
1009 (API complete, but implementation not finished yet).
1010 * Lots of java.net code cleanup.
1011 * Improved documentation.
1012 * Numerous bug fixes in almost every package, and lots of updates for
1013 1.4 functionality.
1014 * Fixed Classpath bugs:
1015 #2944 Incorrect synchronization in java.util.logging.ErrorManager
1016 #6075 java.awt.geom.GeneralPath.getCurrentPoint returns wrong results
1017 #6076 java.awt.geom.GeneralPath constructor sometimes hangs
1018 #6089 java.awt.geom.GeneralPath.getPathIterator does not work
1019 [...]
1020
1021 VM Interface changes:
1022
1023 * Thread has been split in a VM-independent Thread class and a VM-dependent
1024 VMThread class.
1025
1026 New in release 0.06 (2003/22/08)
1027
1028 * Update java.awt peers to GTK+2.
1029 * java.awt.GridBagLayout implementation.
1030 * javax.swing.border implementation.
1031 * java.security and java.security.cert updated to 1.4 spec.
1032 * New JNI native target code layer. See native/target/readme.txt.
1033 * --enable-regen-headers configure flag for automatic jni .h file generation.
1034 * Removed workaround for gcj 3.2 and lower, gcj 3.3+ or jikes 1.18+ is now
1035 needed for compiling.
1036 * Lots of improvements and/or new classes for java.awt, java.awt.dnd,
1037 java.awt.font, java.awt.geom, java.awt.image, java.io, java.math, java.net,
1038 java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf,
1039 javax.swing.text.
1040
1041 VM Interface changes:
1042
1043 * VMClassLoader.loadClass(), the bootstrap classloader called by
1044 Class.forName() and ClassLoader.loadClass(), may now return null when
1045 a class is not found instead of throwing a new ClassNotFoundException.
1046 This is a performance optimization in some cases. This also changes
1047 the Class.forName() reference code.
1048 * Native methods in Class have been moved to VMClass. A few additional
1049 methods are also available in VMClass to provide optional performance
1050 improvements.
1051 * A VM can now supply its own String.intern() strategy through the
1052 VMString class. The supplied VMString reference class implements the
1053 original WeakHashMap strategy.
1054 * Float and Double to/from bits conversion functions can now be supplied by
1055 the VM through VMFloat and VMDouble. Default JNI conversion methods are
1056 supplied.
1057
1058 New in release 0.05 (2003/02/15)
1059 * Supports free Java VMs Jikes RVM and Kissme out of the box, perhaps others.
1060 * Supports GNU Crypto 1.1 as the official provider of cryptographic primitives
1061 and tools for GNU Classpath, available separately from
1062 http://www.gnu.org/software/classpathx/crypto/crypto.html.
1063 * Supports GNU Classpath Tools sub-project of GNU Classpath, official provider
1064 of standard tools such as gjdoc, a javadoc replacement, and others. Future
1065 releases of GNU Classpath will begin to include these tools, available
1066 separately from http://www.gnu.org/software/cp-tools/.
1067 * Java primitives can be used to support AWT native threading, see
1068 the --enable-portable-native-sync configure option which may become the
1069 default in a future release.
1070 * Include file jni.h has been updated to the 1.4 specification.
1071 * VM specific internal types for jobject, jfieldID, and jmethodID are
1072 supported in jni.h. More details can be found by reading the comment
1073 in include/jni.h.in. By default the old definitions are used instead.
1074 * New VM helper class java.io.VMObjectStreamClass which should provide
1075 the hasClassInitializer() method. Previously ObjectStreamClass used
1076 Class.getDeclaredMethod("<clinit>") but according to the spec this
1077 should always throw NoSuchMethodException for class initialization methods.
1078 A JNI reference implementation is provided as
1079 vm/reference/java-io/java_io_VMObjectStreamClass.c
1080 * There have been numerous infrastructure improvements
1081 * Configure option --enable-gjdoc to generate javadoc-like output
1082 * Gjdoc output is included with distribution, see doc/api/html/
1083 * DESTDIR fully supported for install and uninstall
1084 * Runtime.execInternal contract changed to allow for null `env'
1085 and to accept `dir' argument.
1086 * VMObject.getClass() removed. It was never used.
1087 * java.lang.Throwable is now a 'normal' GNU Classpath class that uses the
1088 VM specific java.lang.VMThrowable to get at the VM state and (if needed)
1089 the StackTraceElements for a particular exception. A default implementation
1090 (that does nothing) is provided in vm/reference/java/lang/VMThrowable.java.
1091 * The vm/reference classes from the gnu.vm.stack and their counterparts
1092 ExecutionStack and StackFrame in gnu.java.lang have been removed since they
1093 are not actually part of the VM interface anyway.
1094 * The GPLed com.sun.javadoc classes have been moved to the gjdoc application
1095 from the GNU Classpath Tools project. See for more information the homepage
1096 at: <http://www.gnu.org/software/cp-tools/>.
1097
1098 New in release 0.04 (2002/05/05)
1099 * Additional configure options to disable zip creation and installation as
1100 well as disable gtk peer native compilation.
1101 * Addition of java.nio, java.util.logging, and javax.swing.
1102 * Integration of most or all of the ORP patches to date, the purpose of
1103 which are to make it possible to use JBOSS with ORP and Classpath. This
1104 is still in a testing phase however.
1105 * Significant changes in the reference VM interface that may require
1106 support from the JVMs.
1107 * Lots of bugfixes.
1108
1109 New in release 0.03 (2002/02/08)
1110 * More merges with libgcj have been performed including java.math which now
1111 provides a pure Java implementation of that package.
1112 Current status at <http://gcc.gnu.org/java/libgcj-classpath-compare.html>
1113 * A pure Java implementation (Jazzlib) of java.util.zip is available.
1114 * Added the java.rmi implementation that Transvirtual donated to the FSF.
1115 * Includes jni.h now, eliminating the need to specify a particular VM
1116 via configure.
1117 * No proprietary classes or programs are required to compile.
1118 Compiles out of the box with jikes or gcj.
1119 * Separation of compiling Java source and native libraries through the
1120 configure mechanism. If given no arguments, configure will setup the
1121 subsequent build to only produce Java bytecode (.class files). More
1122 information is available in INSTALLING.
1123 * Support for compiling in a separate directory, as an example you may
1124 cd classpath-0.03; mkdir build; cd build; ../configure; make
1125 * Works with Orp 1.0.9 out of the box. Build instructions can be found at
1126 <http://www.gnu.org/software/classpath/doc/orp.html>
1127 * Lots of bugfixes that were found by using Classpath with the gcj, Orp,
1128 SableVM, KissMe and Jaos VMs. Please use our bugdatabase at
1129 <http://savannah.gnu.org/support/?group_id=85>
1130 * Lots of updates to make Classpath more compliant with the 1.2, 1.3 and 1.4
1131 API specification. The current status can be found at
1132 <http://www.gnu.org/software/classpath/status.html>
1133 * All files are now distributed under the same terms. Added clarification to
1134 GPL exception.
1135
1136 New in release 0.02 (2001/01/06)
1137 * Support for printing exceptions with Japhar 0.09 + patch included in
1138 resource/japhar-0.09.patch.1.
1139 * Typos, assorted bugfixes.
1140
1141 New in release 0.01 (2000/11/20)
1142 * More packages are included now, though many remain untested.
1143 * Support for Japhar 0.09 included.
1144
1145 New in release 0.00 (1999/02/01)
1146 * First official development release of clean room class library for Java
1147 * Following packages included:
1148 -- java.beans

1158 * Code is mostly Java 2 (see JDK 1.2) compatible with some functionality
1159 missing and/or untested.
1160 * Support for Japhar (http://www.japhar.org/) virtual machine is included.
1161 Requires the current Japhar from CVS.
1162 * Extensive javadoc comments for public API included
1163 * Licensed under the GNU Library General Public License (see COPYING.LIB)
1164 * Does not depend on any non-free code - developed in a "clean room"
1165 environment.
