1 New in release 0.95 (Apr 23, 2007)
3 * Full merge of 1.5 generics work.
4 * Added 1.6 java.util.ServiceLoader support.
5 * The ASM library is now included. A separate copy is no longer
6 needed. gjavah works out of the box now.
7 * The setReadTimeout and getReadTimeout methods have been added to
8 java.net.URLConnection. They are now fully implemented for http URLs.
9 * The java.lang.management implementation now includes the new features
11 * java.util.TimeZone now reads time zone information from the system
12 zoneinfo files (see also runtime interface changes below).
13 * The collection classes have been updated to support all the 1.6
15 * java.util.spi 1.6 package has been added and is used in java.text.
16 * Bootstrappable with OpenJDK javac compiler
17 (use configure --with-javac).
18 * Large speedups (and locking behaviour updated) in Graphics2D cairo
20 * Better detection of browser plugin mechanism for mozilla, iceweasel,
21 firefox on various platforms.
22 * Inclusion of generic javadoc classes in tools.zip to support more
23 javadoc processing tools.
24 * Added documentation for command lines options for the included GNU
25 Classpath Tools gjar, gjavah, gnative2ascii, gorbd, grmid,
26 grmiregistry, gserialver and gtnameserv.
28 Runtime interface changes:
30 * gnu.java.lang.management.VMThreadMXBeanImpl has gained three new
31 optional native methods to allow the 1.6 version of the threading
32 bean to be supported. One (getMonitorInfo) fills in information
33 about object monitor locks held by a thread and is only required
34 if the monitoring of object monitor locks is supported by the VM.
35 The other two (findDeadlockedThreads and getLockInfo) are related
36 to ownable synchronizers (part of the java.util.concurrent suite)
37 and only required if monitoring of locks relating to these is
39 * java.util.VMTimeZone and java.util.TimeZone have been refactored
40 to simplify the reference implementation. VMTimeZone.readtzFile()
41 and VMTimeZone.skipFully() have been removed, and a new method
42 VMTimeZone.readSysconfigClockFile() has been introduced.
43 * VMs need to set the system property "gnu.java.util.zoneinfo.dir"
44 to point to the directory where zoneinfo files live. In libgcj
45 this is set to the value of the TZDATA environment variable, or
46 "/usr/share/zoneinfo" if this is not set.
47 * VMFile has been extended to support new 1.6 methods (canExecute,
48 setReadable, setWritable, setExecutable).
50 New in release 0.93 (Dec 8, 2006)
52 * CORBA objects that exist on the same virtual machine and only are connected
53 to another ORB are now accessed directly and no longer via network. It is
54 the same feature that RMI implementation provides. These faster calls should
55 be completely transparent, as the parameters are cloned, where required.
56 Currently the direct calls are only possible for the non-deprecated objects
57 that are connected to the ORB via POA.
58 * The 'javah' tool has been added. It requires the ASM library
59 (see asm.objectweb.org); it can be enabled with the --with-asm
61 * Added the rmi and corbaname URL context factories for JNDI.
62 * Fixes in the JNDI InitialContext now allows to plug-in user implementation.
63 * Removed currentClassLoader method from
64 vm/reference/java/io/ObjectInputStream.java.
65 * Added firstNonNullClassLoader method to
66 vm/reference/gnu/classpath/VMStackWalker.java. VMs are encouraged to
67 provide a more efficient implementation.
68 * Added aton method to vm/reference/java/net/VMInetAddress.java.
69 * NetworkInterface has been implemented for systems that provide the
70 `getifaddrs' function.
71 * java.nio.channels.Selector implementations have been added that use
72 the kqueue notification mechanism on Mac OS X and *BSD, and that use
73 the epoll notification mechanism on Linux 2.6.
74 * java.nio has been refactored to support more non-blocking operations
75 natively. Blocking IO classes have been refactored to call
76 non-blocking classes. Non-blocking accepts, connects, and
77 scatter-gather IO should now be better supported.
78 * HTML support for Swing has been greatly enhanced.
80 Runtime interface changes:
82 * java.net.VMNetworkInterface and java.net.NetworkInterface have been
83 updated to keep native-modified state in the former, and to simplify
84 the native code in our reference implementation.
85 * gnu.java.nio.VMChannel has been expanded to better support native
86 non-blocking IO. Most native state data (such as file descriptor
87 integers) has been abstracted away into private state in the runtime
89 * gnu.java.nio.VMPipe has been similarly changed.
90 * gnu.java.net.VMPlainSocketImpl has been changed to remove some
91 functionality now provided by VMChannel; datagram socket-specific
92 methods have also been moved here, deprecating VMPlainDatagramSocketImpl.
93 * gnu.java.net.VMPlainDatagramSocketImpl removed.
95 New in release 0.92 (Aug 9, 2006)
97 * GConf is used as a backend for java.util.prefs. GNU Classpath
98 thanks to Mario Torre for this contribution!
99 * libjawtgnu.so has been renamed libjawt.so for binary compatibility.
100 libjawt.so should be installed in a VM-specific directory rather
101 than directly in /usr/lib. Proprietary VMs put their libjawt.so
102 implementations in VM-specific directories but search /usr/lib first.
103 If GNU Classpath's libjawt.so is installed in /usr/lib it will create
104 problems for people who use a proprietary VM to run AWT Native
105 Interface applications.
106 * The GdkGraphics2D backend has been made the default. There is no
107 longer an explicit dependency on Cairo, the --enable-gtk-cairo
108 configure option is gone, and GTK 2.8 or higher is now required to
110 * A Mozilla plugin, 'gcjwebplugin', is now included. It introduces a
111 dependency on the Mozilla plugin support headers and libraries.
112 * New java implementations of png and gif imageio readers and writers.
113 * A tools.texinfo document has been created and now includes
119 * Several new tools are now included:
126 A new configure option --enable-tool-wrappers causes wrapper
127 binaries to be built for VMs that support the JNI Invocation API.
128 * We've imported the JSR 166 (concurrency) reference implementation.
129 * javax.sound.midi providers have been added to read and
130 write standard MIDI files.
131 * A javax.sound.sampled .au and .wav file readers have been added.
132 * New Java Virtual Machine Tool Interface header, jvmti.h.
133 * AWT peers for X Windows based on Escher (a pure java X protocol
134 implementation) have been added. So far it supports AWT 1.1 style
135 Graphics, image loading via ImageIO (PNG, GIF and BMP images in this
136 release), top level components as well as mouse and keyboard input.
137 It is capable of running many Swing applications. Graphics2D and
138 AWT widgets are not yet supported with this peer set.
139 * GConf based util.peers backend (see the --enable-gconf-peer and
140 --enable-default-preferences-peer configure options).
141 * Support for batch importing trusted certificates for use with ssl
142 connections (see script/import-cacerts.sh).
143 * NIO scatter-gather channel support.
145 Runtime interface changes:
147 * A new class, VMURLConnection, is used to implement
148 URLConnection.guessContentTypeFromStream. The reference
149 implementation uses libmagic (and falls back to doing nothing if
150 libmagic is not available).
151 * The method gnu.java.io.PlatformHelper.toCanonicalForm() has been
152 replaced with a JNI implementation of VMFile.toCanonicalForm() for
154 * A new class, VMRuntimeMXBeanImpl, is used to implement
155 the low-level support of the runtime management bean.
156 VMs should use it to supply the input arguments and start
157 time of the VM. In addition, one of sun.boot.class.path
158 or java.boot.class.path should be defined by the VM to
159 support the optional boot class path access functionality.
160 * The Unsafe class was moved back to the place expected by the JSR 166
161 reference implementation. We've also added a couple other new VM
162 classes to support the JSR 166 code -- sun.reflect.Reflection and
163 sun.reflect.misc.ReflectUtil.
164 * Another new class, VMClassLoadingMXBeanImpl, is used to implement
165 the low-level support of the class loading management bean.
166 VMs need to supply it with information about how many classes
167 are currently loaded, how many have been unloaded and whether
168 verbose class loading output is on or off. Provision should also
169 be made for the latter to be toggled at runtime.
170 * VMThreadMXBeanImpl is used to implement the low-level support
171 of the thread management bean. Providing this interface requires
172 providing a fair amount of information about threads, including
173 optional time and contention monitoring, and instances of the
174 new ThreadInfo class in java.lang.management. getState() has also
175 been added to the VMThread interface; this is required by the bean
176 as well as java.lang.Thread.
177 * VMMemoryMXBeanImpl is used to implement the low-level support
178 of the memory management bean. Providing this interface requires
179 providing information about the levels of heap and non-heap memory,
180 and the number of objects eligible for garbage collection.
181 * VMCompilationMXBeanImpl is used to allow for optional compilation
182 time support for Just-In-Time compilers.
183 * VMMemoryPoolMXBeanImpl is used to implement the low-level support
184 of the memory pool beans. Providing this interface requires
185 providing memory usage statistics for each supported bean.
186 * VMManagementFactory provides the names of the memory pools,
187 memory managers and garbage collectors maintained by the virtual
188 machine. These are used to create the beans by the ManagementFactory.
189 * VMMemoryManagerMXBeanImpl and VMGarbageCollectorMXBeanImpl provide
190 low-level support for memory managers (including the specific subclass
191 of garbage collecting memory managers). The interfaces for these
192 require no more than enumerating the number of collections and the
193 time spent (for garbage collectors) and a relationship to the memory
194 pools (for all), along with a validity check.
196 New in release 0.91 (May 15, 2006)
198 * Experimental activation (java.rmi.activation) support, including RMI
199 activation daemon and persistent naming service tools.
200 * Experimental printing support: The API implementation of the javax.print
201 packages has been finished and work on the printing provider implementation
202 started. Currently supported features from the Java Print Service API are
203 print service discovery (CUPS registered printers), single document print
204 jobs and support for client-formatted print data. An example application
205 (see: examples/gnu/classpath/examples/print/Demo) has been added to show
206 the API usage for service discovery and printing of files.
207 * The GTKToolkit now gives access to the both the system clipboard and
209 * Custom mouse cursor support has been added to the gtk+ peers. And cursors
210 can now also be set on light-weight components.
211 * Free Swing improvements: Support for OceanTheme has been mostly completed
212 and turned on as default Metal theme. X11-style Copy and Paste behavior in
213 text components with the middle mouse button. Support cursor changes on
214 various components when resizing. Support for Look and Feel window
215 decorations has been added.
216 * Updated locale data information to CLDR 1.3.
217 * Various bugs in Classpath's SecureRandom implementations have been
218 fixed; that class now respects the "securerandom.source" security
219 property and the "java.security.egd" system property.
220 * Support for assistive technologies has been added to AWT and Swing.
222 Runtime interface changes:
224 * A new class, VMArray, is now available which separates the native
225 array creation method from java.lang.reflect.Array.
226 * A new class, gnu.classpath.Unsafe, is provided for handling the
227 new low-level operations required by java.util.concurrent.
228 * The reference implementations of Method, Constructor, and Field
229 now have a new native getModifiersInternal() method. The public
230 getModifiers() method in each case has been rewritten in terms of
232 * The reference implementation of VMThread has been updated to handle
233 the new Thread.UncaughtExceptionHandler support.
234 * A new class, java.security.VMSecureRandom, is now available that is
235 used to generate random numbers for seeding cryptographically-secure
236 pseudo-random number generators.
237 * VMClass and the reference implementations of Method, Constructor and Field
238 now include a number of 1.5 methods imported from the generics branch.
239 These are all optional (in the sense that the methods associated with them
240 merely fail on use if the VM doesn't provide them, rather than the
241 VM failing altogether), but VMs should aim to support them where possible.
242 * The implementation of java.lang.instrument has been merged to the main
243 branch from the generics branch.
244 * The VM interfaces of the main branch and the generics branch are now
245 consistent with one another. As a result, the main branch includes an
246 additional environ() function in VMSystem and an additional argument has
247 been added to nativeSpawn() in VMProcess.
248 * Annotation support is now available in the main branch, if the VM supports
249 it. The VM should implement VMClass.getDeclaredAnnotations,
250 Constructor.getAnnotation, Constructor.getDeclaredAnnotations,
251 Field.getAnnotation, Field.getDeclaredAnnotations, Method.getAnnotation and
252 Method.getDeclaredAnnotations.
253 * java.lang.Package now has a new constructor that takes the defining
254 ClassLoader as an extra argument. If you use a custom version of
255 VMClassLoader, please switch it to use this constructor.
256 * The reference implementation of VMClassLoader.getBootPackages() now
257 reads the META-INF/INDEX.LIST resource using the java.boot.class.path
260 New in release 0.90 (March 6, 2006)
262 * Free Swing improvements: JTable columns are rearrangeable and
263 resizeable with mouse. Painting and scrolling are now much
264 faster. Plain text components now support highlighting and
265 copy+paste to the system clipboard. Support for styled text has been
266 improved, including some very basic HTML support. JFileChooser is
267 now usable. Global event dispatching has been implemented. Memory
268 consumption of Swing components has been reduced. Lots of general
269 bugfixes. Added new system property to turn off Graphics2D use in
270 Swing, even if Graphics2D is available: gnu.javax.swing.noGraphics2D
272 * AWT. Improved support for mixing "lightweight" and "heavyweight"
273 Components in Containers. Better support for dynamically updated
274 menus. Better 1.0 event model support for Scrollbars. Better class
275 documentation of gtk+ awt peers.
277 * GNU Crypto and Jessie have been merged into GNU Classpath; this
278 provides Classpath with a wide array of cryptographic algorithms
279 (ciphers, message digests, etc.) and implementations of SSL version
280 3 and TLS version 1. These roughly complement the public
281 `java.security.' `javax.crypto,' and `javax.net.ssl' packages, and
282 are service providers implementing the underlying algorithms.
284 * Updated HTTP and FTP URLConnection protocol handlers. HTTPS support
287 * Unicode 4.0.0 is supported. Character now includes support for using
288 ether a char or an int to identify code points.
290 * More correct handling of Object methods and serialization support
291 for Proxy and abstract classes.
293 * The new folder tools includes GIOP and RMI stub and tie source code
294 generators, IOR parser and both transient and persistent GIOP naming
297 * Added experimental support for dynamic creation of the RMI stubs
298 using proxy classes. The rmic compiler is no longer required (unless
299 for research and specific stubs).
301 * XML validaton support for RELAX NG and W3C XML schema namespace
302 URIs. RELAX NG pluggable XML schema datatype library API and an
303 implementation for XML Schema Datatypes
304 (http://www.w3.org/TR/xmlschema-2/).
306 * Updated StAX implementaton to be compatible with final JSWDP 2.0.
308 * The default back end for java.util.prefs has been changed. The new
309 default is capable of saving and restoring preferences to and from
312 * javax.imageio.plugins.bmp implementation.
314 * Added --enable-collections configure option which builds
315 "collections.jar", a 1.1 VM compatibility jar.
317 * gnu.regexp updated from GNU/Posix syntax to support util.regex
318 syntax including various Unicode blocks, categories and properties.
320 Runtime interface changes:
322 * A new class, VMMath, is now available which separates the native
323 mathematical functions from java.lang.Math. The previous fdlibm
324 implementation now forms the reference material for this class.
326 * Updated VMObjectInputStream class to return Thread context class
327 loader if no other class loader is found.
329 * Updated documentation on InstrumentationImpl in vmintegration guide.
331 New in release 0.20 (Jan 13, 2006)
333 * New StAX pull parser and SAX-over-StAX driver. Lots of DOM, SAX/StAX,
334 XPath and XSLT improvements. Support for XInclude and XML Base added.
335 Conformance is now regularly tested against various test-suites at
336 http://builder.classpath.org/xml/ See also doc/README.jaxp.
338 * Full beans XMLEncoder implementation.
340 * javax.sound.sampled implementation.
342 * javax.print.attribute and javax.print.event implementated.
344 * Lots of new datatransfer, print swing and swing.text work and optimization.
346 * Additional 1.5 support. Including new (separate) generic branch release.
348 * SecurityManager cleanups and start of review of all Permission checks
349 (includes adding lots of new checks to the Mauve test-suite).
351 * Buildable on cygwin.
353 * Fully buildable as "in-workspace" library-plus-vm inside (native) Eclipse
354 see http://developer.classpath.org/mediation/ClasspathHackingWithEclipse
356 * Full example that shows a real world CORBA and Free Swing implementation.
357 See examples/gnu/classpath/examples/CORBA/swing/README.html
359 * A list of bug fixes can be found at:
360 http://gcc.gnu.org/bugzilla/buglist.cgi?product=classpath&target_milestone=0.20
362 Runtime interface changes:
364 * New method VMStackWalker.getClassLoader() was added to avoid an infinite
365 loop between getCallingClassLoader() and Class.getClassLoader().
367 * The included fdlibm implementation has seen several cleanups to handle
368 new architectures and namespacing issues (in particular for ppc, darwin
369 and non-C99 compilers). Please double check any arithmetic test against
370 new platforms/runtimes.
372 * The gnu.java.net.Plain[Datagram]Socket implementations have been
373 turned into VM reference classes with JNI/Posix implementations.
375 New in release 0.19 (Nov 2, 2005)
377 * The Swing RepaintManager has been reworked for more efficient painting,
378 especially for large GUIs.
380 * The Swing layout manager OverlayLayout has been implemented, the BoxLayout
381 has been rewritten to make use of the SizeRequirements utility class and
382 caching for more efficient layout.
384 * Improved accessibility support for Swing.
386 * The java.net.HttpURLConnection implementation no longer buffers the
387 entire response body in memory. This means that response bodies
388 larger than available memory can now be handled.
390 * The Andrew Watson, Vice President and Technical Director of the Object
391 Management Group, has officially assigned us 20 bit Vendor Minor Code Id:
392 0x47430 ("GC") that will mark remote Classpath - specific system exceptions.
393 Obtaining the VMCID means that GNU Classpath now is a recogniseable type of
394 node in a highly interoperable CORBA world.
396 * Classpath now includes the first working draft to support the RMI over
397 IIOP protocol. The current implementation is capable for remote invocations,
398 transferring various Serializables and Externalizables via RMI-IIOP protocol.
399 It can flatten graphs and, at least for the simple cases, is interoperable
402 * Qt4 configury switches for OS-X. Additional to the --enable-qt-peer, OS-X
403 users with a Qt4 installation can build the qt-peers with the argument
404 --with-qt4dir=<Qt4-installation-dir>.
406 * Significant progress has been made in the implementation of the
407 javax.swing.plaf.metal.* package, with most UI delegates in a working state
408 now. Please test this with your own applications and provide feedback that
409 will help us to improve this package.
411 * The GUI demo (gnu.classpath.examples.swing.Demo) has been extended to
412 highlight various features in our free-swing implementation. And includes
413 a look and feel switcher (Metal default, Ocean or GNU).
415 Runtime interface changes:
417 * Changed implementation of VMClassLoader.getPackage(s) : new method
418 VMClassLoader.getBootPackages should be implemented by the vm, and sould
419 return a string array of boot package names ("java.lang", "java.net", ...).
420 Feedback from vm implementors for usability and relevance of the
421 getBootPackages method would be greatly appreciated.
423 New in release 0.18 (Sep 6, 2005)
425 * GNU JAWT implementation, the AWT Native Interface, which allows direct
426 access to native screen resources from within a Canvas's paint method.
427 GNU Classpath Examples comes with a Demo, see examples/README.
428 * awt.datatransfer updated to 1.5 with supports for FlavorEvents.
429 The gtk+ awt peers now allow copy/paste of text, images, uris/files
430 and serialized objects with other applications and tracking
431 clipboard change events with gtk+ 2.6 (for gtk+ 2.4 only text and
432 serialized objects are supported). A GNU Classpath Examples
433 datatransfer Demo was added to show the new functionality.
434 * org.omg.PortableInterceptor and related functionality in other packages
436 - The sever and client interceptors work as required since 1.4.
437 - The IOR interceptor works as needed for 1.5.
438 * The org.omg.DynamicAny package is completed and passes the prepared tests.
439 * The Portable Object Adapter should now support the output of the
440 recent IDL to java compilers. These compilers now generate servants and
441 not CORBA objects as before, making the output depended on the existing
442 POA implementation. Completing POA means that such code can already be
443 tried to run on Classpath. Our POA is tested for the following usager
445 - POA converts servant to the CORBA object.
446 - Servant provides to the CORBA object.
447 - POA activates new CORBA object with the given Object Id (byte array)
448 that is later accessible for the servant.
449 - During the first call, the ServantActivator provides servant for this
450 and all subsequent calls on the current object.
451 - During each call, the ServantLocator provides servant for this call
453 - ServantLocator or ServantActivator forwards call to another server.
454 - POA has a single servant, responsible for all objects.
455 - POA has a default servant, but some objects are explicitly connected
456 to they specific servants.
457 The POA is verified using tests from the former cost.omg.org.
458 * The javax.swing.plaf.multi.* package is now implemented.
459 * Editing and several key actions for JTree and JTable were implemented.
460 * Lots of icons and look and feel improvements for Free Swing basic and
461 metal themes were added. Try running the GNU Classpath Swing Demo in
462 examples (gnu.classpath.examples.swing.Demo) with:
463 -Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel
464 -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel
465 * Start of styled text capabilites for java.swing.text.
466 * NIO FileChannel.map implementation, fast bulk put implementation for
467 DirectByteBuffer (speeds up this method 10x).
468 * Split gtk+ awt peers event handling in two threads and improve gdk lock
469 handling (solves several AWT lock ups).
470 * Speed up awt Image loading.
471 * Updated TimeZone data against Olson tzdata2005l.
472 * Make zip and jar UTF-8 "clean".
473 * "native" code builds and compiles (warning free) on Darwin and Solaris.
475 Runtime interface changes:
477 * All native resource "pointers" in the VM interface classes are now exposed
478 as gnu.classpath.Pointer objects. This might impact runtimes that
479 optimize and support java.nio.DirectByteBuffers. Creating these classes
480 and accessing the contents as void * pointers for the native reference JNI
481 implementation is done through the JCL_NewRawDataObject and JCL_GetRawData
483 * Simplified the Class/VMClass interface.
484 * Removed loadedClasses map from ClassLoader. It's now the VMs responsibility
485 to manage the list of defined and loaded classes for each class loader.
486 * Moved native methods from java.lang.reflect.Proxy to VMProxy.
487 * Added hook to VMClassLoader to allow VM to do class caching.
489 New Untested/Disabled Features:
491 The following new features are included, but not ready for production
492 yet. They are explicitly disabled and not supported. But if you want
493 to help with the development of these new features we are interested
494 in feedback. You will have to explicitly enable them to try them out
495 (and they will most likely contain bugs). If you are interested in any
496 of these then please join the mailing-list and follow development in
499 * QT4 AWT peers, enable by giving configure --enable-qt-peer.
500 * JDWP framework, enable by deleting the jdwp references from
501 lib/standard.omit and vm/reference/standard.omit. No default
502 implementation is provided. Work is being done on gcj/gij integration.
503 * StAX java.xml.stream, enable by deleting the gnu.xml.stream and
504 java.xml.stream references in lib/standard.omit.
506 New in release 0.17 (Jul 15, 2005)
508 * gnu.xml fix for nodes created outside a namespace context.
509 * Add support for output indenting and cdata-section-elements output
510 instruction in xml.transform.
511 * xml.xpath corrections for cases where elements/attributes might have
512 been created in non-namespace-aware mode. Corrections to handling of
513 XSL variables and minor conformance updates.
514 * DefaultMutableTreeNode preorder, postorder, depthFirst and breadthFirst
515 traversal enumerations implemented.
516 * JInternalFrame colors and titlebar draw properly.
517 * JTree is working up to par (icons, selection and keyboard traversal).
518 * JMenus were made more compatible in visual and programmatic behavior.
519 * JTable changeSelection and multiple selections implemented.
520 * JButton and JToggleButton change states work properly now.
521 * JFileChooser fixes.
522 * revalidate and repaint fixes which make Free Swing much more responsive.
523 * Correctly handle system call interrupts and timeouts in native nio
525 * MetalIconFactory implemented.
526 * Handle image loading errors correctly for gdkpixbuf and MediaTracker.
527 * Added Tree World to GNU Classpath examples Free Swing demo.
528 * FileChannel.lock() and FileChannel.force() implemented.
529 * java.util.logging.FileHandler now rotates files.
530 * Better handle GDK lock. Properly prefix gtkpeer native functions (cp_gtk).
531 * Corba bug fixes and documentation updates.
532 * Updated gcj build infrastructure.
533 * Documentation fixes all over the place.
534 See http://developer.classpath.org/doc/
535 * VM Integration Guide updates with a full section on VM/Classpath hooks.
537 New in release 0.16 (Jun 30, 2005)
539 * Better GTK scrollbar peer implementation when using GTK >= 2.6.
540 * GdkGraphics2D has been updated to use Cairo 0.5.x APIs.
541 * BufferedImage and GtkImage rewrites. All image drawing operations
542 should now work correctly (flipping requires gtk+ >= 2.6)
543 * Future Graphics2D, Image and Text work is documented at:
544 http://developer.classpath.org/mediation/ClasspathGraphicsImagesText
545 * Free Swing Top-Level Compatibility. JFrame, JDialog, JApplet,
546 JInternalFrame, and JWindow are now 1.5 compatible in the sense that you
547 can call add() and setLayout() directly on them, which will have the same
548 effect as calling getContentPane().add() and getContentPane().setLayout().
549 * The JTree interface has been completed. JTrees now recognizes mouse clicks
550 and selections work, but the visual implementation is not yet complete.
551 Work on expansion and collapsing of the tree nodes is being implemented.
552 * BoxLayout works properly now.
553 * Fixed GrayFilter to actually work.
554 * Metal SplitPane implemented.
555 * Lots of free swing text and editor stuff work now.
557 * When gtk+ 2.6 or higher is installed the default log handler will produce
558 stack traces whenever a WARNING, CRITICAL or ERROR message is produced.
560 * The CORBA implementation is now a working prototype that should support
561 features up till 1.3 inclusive.
562 We would invite groups writing CORBA dependent applications to
563 try Classpath implementation, reporting any possible bugs.
565 The CORBA prototype is interoperable with Sun's implementation v 1.4,
566 transferring object references, primitive types, narrow and wide
567 strings, arrays, structures, trees, abstract interfaces and
568 value types (feature of CORBA 2.3) between these two platforms.
569 The remote exceptions are transferred and handled correctly.
570 The stringified object references (IORs) from various sources are
572 The transient (for current session) and permanent (till jre restart)
574 Both Little and Big Endian encoded messages are accepted.
575 The implementation is verified using tests from the former cost.omg.org.
576 The current release includes working examples (see the examples directory),
577 demonstrating the client-server communication, using either CORBA Request
578 or IDL-based stub (usually generated by a IDL to java compiler).
579 These examples also show how to use the Classpath CORBA naming service.
580 The IDL to java compiler is not yet written, but as our library must be
581 compatible, it naturally accepts the output of other idlj implementations.
583 * New --with-vm-classes configure option, and new 'build' setting
584 for --with-glibj. (Only for integrators.)
586 Runtime interface changes:
588 * Start of a generic JDWP framework in gnu/classpath/jdwp.
589 This is unfinished, but feedback (at classpath@gnu.org) from runtime
590 hackers is greatly appreciated. Although most of the work is currently
591 being done around gcj/gij we want this framework to be as VM neutral as
592 possible. Early design is described in:
593 http://gcc.gnu.org/ml/java/2005-05/msg00260.html
594 * Native method VMClass.getModifiers() now takes an additional
596 * Deprecated native method VMClassLoader.defineClass(ClassLoader,
597 String, byte[], int, int) has been replaced by
598 VMClassLoader.defineClass(ClassLoader, String, byte[], int, int,
600 * VMClassLoader.loadClass(String name, boolean resolve) is now native,
601 replacing the former version which just returned null.
602 * Deprecated native method VMClassLoader.getPrimitiveClass(String) has
603 been replaced by new native method VMClassLoader.getPrimitiveClass(char).
604 * Previously empty implementations of methods VMThread.countStackFrames(),
605 VMThrowable.fillInStackTrace(), and VMThrowable.getStackTrace() have
606 been removed; these methods are now native methods.
607 * Fields "exceptionTypes" and "parameterTypes" have been removed from
608 Contructor.java and getExceptionTypes() and getParameterTypes() are
611 New in release 0.15 (Apr 29, 2005)
613 * The old character encoding framework (gnu.java.io.EncodingManager)
614 has been replaced by a system based completely on nio.charset
615 providers. Many converters have been added, both the io, lang and nio
616 frameworks now use the same set of converters and the whole character
617 stream framework (Readers and Writers) have been optimized. For some
618 workloads this leads to 2x till 20x speedups.
620 The default charsets supported are:
622 Cp424, Cp437, Cp737, Cp775, Cp850, Cp852, Cp855, Cp857, Cp860, Cp861,
623 Cp862, Cp863, Cp864, Cp865, Cp866, Cp869, Cp874, ISO_8859_1, ISO_8859_13,
624 ISO_8859_15, ISO_8859_2, ISO_8859_3, ISO_8859_4, ISO_8859_5, ISO_8859_6,
625 ISO_8859_7, ISO_8859_8, ISO_8859_9, KOI_8, MS874, MacCentralEurope,
626 MacCroatian, MacCyrillic, MacDingbat, MacGreek, MacIceland, MacRoman,
627 MacRomania, MacSymbol, MacThai, MacTurkish, US_ASCII, UTF_16, UTF_16BE,
628 UTF_16Decoder, UTF_16Encoder, UTF_16LE, UTF_8, UnicodeLittle, Windows1250,
629 Windows1251, Windows1252, Windows1253, Windows1254, Windows1255,
630 Windows1256, Windows1257, Windows1258.
632 Many more encoding are supported through the new IconvProvider
633 depending on the platform iconv support. GNU libiconv is recommended.
634 The IconvProvider is currently not enabled by default. To enable it
635 define the system property gnu.classpath.nio.charset.provider.iconv=true.
636 Some runtimes might choose to enable this by default by setting it
637 through VMSystemProperties. We would like to get feedback on whether
638 enabling or disabling the IconvProvider by default results in the
641 * Free swing metal and pluggable look and feels have been improved.
642 The GNU Classpath free swing example can now be run with different
643 "skins" by setting the system property swing.defaultlaf to the GNU,
644 Basic or Metal look and feel.
646 * Some of the org.omg.CORBA classes and packages have now been
647 implemented. The Savannah bug tracker contains additional tasks for
648 which we are seeking help.
650 * Fixed compatibility problems in the java.beans which affected
651 Eclipse's Visual Editor Project.
653 * New completely lock free (Inheritable)ThreadLocal implementation.
655 * javax.swing.text.rtf framework added which can handle simple (plain)
658 * Support for parsing html files into Level 2 Document Object Model
659 (org.w3c.dom.html2 and javax.swing.text.html.parser). And a start of
660 javax.swing.text.html framework added.
662 Runtime interface changes:
664 * jni.h changed to better support compiling runtimes implementing jni;
665 see VM integration guide for details.
666 * New --enable-default-toolkit option to configure can be used to set
667 the fully qualified class name of the default AWT toolkit to use.
668 If not given, the old default of gnu.java.awt.peerk.gtk.GtkToolkit
670 * New --disable-core-jni option can be used to disable building the
671 "core" JNI libraries. This is primarily useful if your VM can use the
672 Gtk peers but not the core JNI libraries.
673 * New system property "gnu.classpath.boot.library.path" can be specified
674 to define the location of the JNI libraries. It is by all means meant
675 ONLY for VM implementors and GNU Classpath hackers. See the hacking
676 guide for more information.
677 * The helper methods currentLoader() and allocateObject() for
678 java.io.ObjectInputStream have been moved to a VMObjectInputStream class.
679 Reference implementations are provided.
680 * java.net.InetAddress now uses VMInetAddress for runtime/platform
681 specific methods getLocalHostname(), getHostByAddr() and
682 getHostByName(). java.net.NetworkInterface now uses VMNetworkInterface
683 for runtime/platform specific getInterfaces() support. Default
684 (Posix/GNU JNI) implementations are provided.
685 * VMClass has a new method getModifiers(Class, boolean) which can be
686 used to get the real modifiers for an inner class or the ones
687 specified by the InnerClasses attribute.
688 * All (possible) runtime specific methods of Object and Double are now
689 in VMObject and VMDouble. Where possible generic reference
690 implementations are provided.
691 * The reference implementation of VMClassLoader now handles zip files
692 on the boot loader class path in getResources().
696 New in release 0.14 (Feb 25, 2005)
698 * Character encoders and decoders have been added for:
699 iso-8859-6 (arabic), iso-8859-7 (greek), iso-8859-8 (hebrew),
700 iso-8859-9 (latin-5), iso-8859-13, iso-8859-15 (latin-9), cp1047 (ebcdic),
701 ebcdic-xml-us,ascii, windows-1250, windows-1252, UTF-16BE (Big Endian),
702 UTF-16LE (Little Endian), UTF-32BE (Big Endian), UTF-32LE (Little Endian).
703 * Full documentation for all classes can be generated (again) by using
704 the --with-gjdoc configure option.
705 * javax.awt.imageio support through gdkpixbuf.
707 Runtime interface changes:
709 * VMSecurityManager has been replaced by gnu.classpath.VMStackWalker.
710 currentClassLoader() is no longer needed, and there are also two new
711 methods with non-native implementations. VM implementors are encouraged
712 to provide more efficient versions.
713 * VMRuntime.nativeLoad() now takes an additional ClassLoader parameter.
715 New in release 0.13 (Jan 6, 2005)
717 * The http url protocol handler has been replaced with a full HTTP/1.1
718 version from GNU inetlib.
719 * A new ftp url protocol handler has been added also from GNU inetlib.
720 * java.beans has been updated to 1.4 including support for XMLEncoder
722 * The java.util.Locale support is now based on the Common Locale Data
723 Repository (CLDR) Project (see http://www.unicode.org/cldr/).
724 GNU Classpath provides support for more than 250 locales now.
725 This new support is experimental and the GNU Classpath hackers are
726 working together with runtime developers and the unicode consortium
727 to improve them in the future.
728 If your runtime misdetects your locale or if the default locale gives
729 problems please try running with -Duser.language=en and -Duser.region=US
730 to fall back on a known good locale.
731 * Added implementations of javax.xml (JAXP 1.3), org.xml.sax (SAX2) and
732 org.w3c.dom (DOM Level 3) interfaces. It is possible to switch between
733 different implementations AElfred2, GNU DOM, GNU XSL, libxmlj SAX,
734 libxmlj DOM and libxmlj XSL by setting different system properties.
735 Also provided is a preliminary XPath 1.0 implementation.
736 The libxmlj versions are build around libxml2 and libxslt and have to
737 be enabled during build time by the --enable-xmlj configure flag.
738 The current support is equal to the last released GNU JAXP 1.3 release.
739 These packages will be maintained as part of the GNU Classpath core classes
740 in the future. For more information, conformance results and documentation
741 on selecting different implementations see doc/README.jaxp.
742 * More AWT accessible support.
743 * AWT gtk+ peers component layout, dialog placement, keyboard focus
744 handling and text positioning have been improved.
745 * ImageIO interfaces are more complete.
746 * JList, JTable and JTree have been hugely improved.
747 * java.awt.Robot support with GdkRobot in the gtk+ awt peers.
748 Needs XTest Extension (libXtst) XServer support.
749 * New --disable-examples configure argument.
751 Runtime interface changes:
753 * Added a new method (VMRuntime.enableShutdownHooks) that enables the VM
754 to lazily register an exit handler.
755 * The java.lang.Class constructor now automatically sets the protection
756 domain for array classes, based on the protection domain of the component
758 * New gnu.classpath.VMSystemProperties class. This replaces the
759 system properties initialization in VMRuntime. Note that it is
760 now the VMs responsibility to set one additional property:
761 gnu.cpu.endian should be set to "big" or "little".
762 * VMRuntime.nativeGetLibname() has been renamed to VMRuntime.mapLibraryName()
763 and has only one argument, the name of the library.
764 * String and StringBuffer now call VMSystem.arraycopy() directly and don't
765 go through java.lang.System. Be careful to not initialize java.lang.System
766 early in the bootstrap sequence in your VM runtime interface classes.
767 * Some (wrong) documentation about the behavior of VMThread.sleep(0, 0)
768 has been updated. Also, VMThread.sleep() now has a default non-native
769 implementation, but it is a generic implementation that ignores the
770 nano-seconds argument. Runtime hackers are encouraged to provide a more
772 * There is prelimenary support for nio direct byte buffers.
773 See VMDirectByteBuffer. Please contact the GNU Classpath mailinglist when
774 you add support for this to your runtime.
776 New in release 0.12 (Nov 14, 2004)
778 * GNU Classpath's JAR implementation now has preliminary support for
779 signed entries, for so called "signed JAR" file support. Signed JAR
780 files are one of the key security features of managed runtimes, and
781 allows code to run privileged given unforgeable proofs of identity.
782 * A much improved version of X.509 certificates has been added,
783 including a robust certificate path checking algorithm. Also
784 included is an implementation of the RSA signature scheme.
785 * Full java.awt.color implementation, with all standard ICC profiles,
786 except for PhotoYCC color space.
787 * java.beans 1.4 updates and bug fixes.
788 * java.awt.image support updated to 1.4.
789 * Improved build process. Uses less memory with gcj and C code is
790 buildable with -Werror on most platform. Please configure with
791 --enable-Werror and report any remaining issues.
792 * Big-endian (PowerPC) fixes for native awt GTK+ peers.
793 * Checkstyle support, see scripts/checkstyle-config.xml.
794 * Better AWT focus management fro GTK+ peers.
795 * Much faster and better fonts support
796 (for both gdk Graphics and cairo Graphics2D)
797 * AWT Choice fixes for hidden components.
798 * HTTP Connection Handler fixes for POST support.
799 * Much fuller collection documentation.
800 * Lots of Calendar bug fixes.
801 * More javax.imageio support.
802 * Better AWT Help MenuBar support.
803 * Lookahead support for regular expressions.
804 * Serialization object stream fixes for multiple ClassLoader scenarios.
805 * Swing TabbedPane, ColorChooser and ComboBox improvements.
806 * Start of JTree functionality.
807 * Improved Eclipse 3 support for GNU Classpath based runtimes.
809 Runtime interface Changes:
811 * New --enable-java-lang-system-explicit-initialization configuration
812 option. (Warning, will be replaced in next release, please consult
814 * The reference implementation of VMClassLoader has default
815 implementations for getResource(s) and provides support for a new
816 default getSystemClassLoader implementation.
818 New in release 0.11 (Sep 13, 2004)
820 * javax.swing.Spring and SpringLayout support.
821 * Added pluggable look and feel support for BasicTextFieldUI and
822 BasicToolBarSeparatorUI.
823 * java.swing.text support for (Default and Layered) Highlighter, FieldView,
824 PlainView, TabExpander and TabableView added.
825 * Start of JTable and JTree implementation.
826 * Internal Swing frames work.
827 * JMenu and JPopupMenu work.
828 * New gtk+ AWT FileDialog peer now based on gtk+2.4 or higher.
829 * java.awt.image LookupTables and kernel support.
830 * Improved java.awt.image.BufferedImage support.
831 * AWT 1.0 event model support.
832 * GNU Classpath now comes with some example programs (see examples/README).
833 * New javax.crypto, javax.crypto.interfaces, javax.crypto.spec, javax.net,
834 javax.net.ssl, javax.security.auth, javax.security.auth.callback,
835 javax.security.auth.login, javax.security.auth.x500, javax.security.sasl
836 and org.ietf.jgss packages are now officially part of GNU Classpath.
837 Extra crypto algorithms can be obtained from the GNU Crypto project,
838 a full TLS implementation is provided by the Jessie project.
839 http://www.gnu.org/software/gnu-crypto/
840 http://www.nongnu.org/jessie/
841 * Frame.setIconImage() support.
842 * AWT GDKGraphics scaling.
843 * New configure flag --enable-gtk-cairo to build Graphics2D implementation
844 build on cairo and pangoft2. Enabled at runtime by defining the system
845 property gnu.java.awt.peer.gtk.Graphics=Graphics2D.
846 * javax.swing.JSpinner implemented.
847 * Extensive documentation update for java.util collection classes.
848 * java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented.
849 * GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and
850 tool integrators are encouraged to directly integrate GNU JAXP.
851 This release has been tested against GNU JAXP 1.1.
852 http://www.gnu.org/software/classpathx/jaxp/jaxp.html
853 * JColorChooser, JComboBox and JTextField implemented, including example
854 uses in GNU Classpath Examples swing Demo.
856 Runtime interface Changes:
858 * java.lang.Compiler now uses the new java.lang.VMCompiler; there is
859 a reference implementation that most VMs can use.
860 * java.lang.VMSystem has a new getenv(String) method and a reference C/JNI
861 implementation that should work on most Posix like systems.
862 * java.util.TimeZone has been split into a platform independent class and
863 a platform dependent class VMTimeZone. GNU Classpath comes with a generic
864 way to get at the default time zone for Posix/GNU-like platforms.
865 * [VM]AccessController improvements. In particular it handles
866 `doPrivileged' calls better, and allows for recursive `doPrivileged'
867 calls in the same Thread. (see vm/reference/java/security/)
869 New in release 0.10 (Jul 9, 2004)
871 * java.net.URL now uses application classloader to load URLStreamHandlers
872 and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
873 * java.io.File.deleteOnExit() implementation.
874 * java.text multiple new features and bug fixes
875 (only 2 out of the 1000+ java.text Mauve tests now fail).
876 * Better (non-black) default AWT System colors.
877 * AWT lists use GTK treeviews.
878 * Proper AWT focus management has been implemented.
879 * Swing menus and scrollpanes are beginning to work.
880 * Swing splitpanes, dialogs and internal frames were added.
881 * Swing repainting / double buffering was redone.
882 * Font management and Pango DPI conversion fixes.
883 * A lot of AWT imaging and event bugs have been picked out.
884 * More of javax.swing.text has been implemented.
885 * javax.swing.Timer has been reimplemented.
886 * java.security.AccessController has been implemented
887 (see runtime section).
888 * The default java.lang.SecurityManager now uses AccessController.
889 * New java.beans.Statement and Expression implementations.
890 * Small FileChannel implementation speed improvement for traditional
892 * Regenerated all included JNI header files with gcjh (3.5 CVS),
893 removes extra extern modifier and allows stricter compiler warning.
894 * More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
895 -Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
896 made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
897 * Double.toString() and Float.toString() now work properly on 64-bit
899 * PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
900 * Build system refactored and removed old Japhar specific support.
901 * The gnu.java.awt.EmbeddedWindow class has been improved, and now
902 supports embedding AWT windows in other top-level X windows.
903 This functionality is required by gcjwebplugin.
904 * gcjwebplugin, an applet viewer that can be embedded into several web
905 browsers, has been extensively tested with this release of classpath.
906 (See http://www.nongnu.org/gcjwebplugin/)
907 * Runtime environments based on GNU Classpath 0.10 should be able to
908 start up Eclipse 3.0 out of the box now.
910 Runtime interface Changes:
912 * VMProcess.destroy() default implementation fixes.
913 * Fixed the "portable native sync" code; it had been broken since
914 Classpath release 0.06, when we upgraded to GTK+2.
915 Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses
916 the platform's native threading model -- pthreads in most cases.
917 If the Java runtime doesn't use the native threading model, then you should
918 specify --portable-native-sync when configuring Classpath, so that GLIB will
919 use the Java threading primitives instead. (For a superior alternative,
921 * The VM can set the system property
922 gnu.classpath.awt.gtk.portable.native.sync instead of using the
923 --portable-native-sync configure-type option.
924 See doc/vmintegration.texinfo for details.
925 * We intend that the next release of GNU Classpath will require the VM
926 to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for
927 one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
928 If this poses problems, please raise them on the classpath mailing list.
929 * The reference implementation of VMThread.holdsLock(Object) now has
930 a default implementation written in java. For efficiency and to
931 prevent spurious wakeups a real 'native' runtime version can be supplied.
932 * There is a new java.security.VMAccessController class that runtimes need
933 to implement to properly support SecurityManagers. The default
934 implementation that comes with GNU Classpath makes sure that ANY attempt
935 to access a protected resource is denied when a SecurityManager is
936 installed. Which is pretty secure, but also no very useful.
937 Please see the documentation in
938 vm/reference/java/security/VMAccessController.java,
939 and please give feedback on the GNU Classpath mailinglist whether or not
940 the current AccessController framework is flexible enough.
942 New in release 0.09 (May 2, 2004)
944 * Includes updated GNU JAXP version from 2004-02-01.
945 * Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean.
946 * java.io is now implemented by delegating most tasks directly to java.nio.
947 * Reworked/Optimized implementations of java.nio.Buffer and subclasses.
948 * New javax.print, javax.print.attribute[.standard] and javax.print.event
949 packages and classes.
950 * java.text attributed iterators support.
951 * New javax.imageio, javax.imageio.event and javax.imageio.spi packages and
953 * GNU Classpath can now load service providers that are described via
954 META-INF/services/* resources in extension JARs. This is useful for
955 implementing the various APIs that are supposed to be extensible via
956 custom plugins. For details, please see the documentation of
957 gnu.classpath.ServiceFactory.
958 Application developers are strongly discouraged from calling glibj
959 internal packages. Instead, they might want invoke the newly implemented
960 javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard
961 method for loading plug-ins.
962 * New developers wanting to help the GNU Classpath project might want to
963 review the greatly expanded Hacker Guide included in the doc directory
964 or online at http://www.gnu.org/software/classpath/docs/hacking.html
965 Also the FAQ has been expanded. And when working from CVS you can now use
966 a simple autogen.sh script to get all autotools magic done automagically.
967 * New configure option --with-glibj which defines how to install the glibj
968 class files as zip, as flat directory files or both (zip|flat|both)
969 [default=zip]. When working with multiple runtimes some of which might
970 not support bootstrap classes in zip files the --with-glibj=both option
971 is recommended (this does take extra disc space).
972 * Two big code drops from the libgcj gui branch updating various java.awt
973 and javax.swing classes.
974 * Multiple java.net.InetAdress fixes and java.rmi fixes.
975 * ServerSocket.accept() now restarts listening when system call interrupted.
976 * Much cleanups to make standard API doc valid XHTML (not completed yet).
977 * A scan for unused variables and non-static invocation of static methods
978 turned up a couple of subtle bugs which have now all been fixed.
979 * The Mauve testsuite has been cleaned up considerable and lots of issues
980 in the GNU Classpath core class implementation have been fixed.
982 VM Interface changes:
984 * java.lang.Class/VMClass interface was changed. The interface now no
985 longer requires an instance of VMClass for each Class instance. Instead
986 the field vmdata in Class is now of type Object.
987 * GNU Classpath now assumes that JNI calls SetXField can modify final
988 fields. This was previously used silently for System.in/out/err and should
989 be considered as a feature now.
990 * A new VMProcess and a sample JNI C implementation are now provided to
991 make Runtime.exec() work out of the box on some systems. This requires
992 a small change to VMRuntime.exec() when a runtime wants to use it as the
993 default java.lang.Process implementation.
994 * The implementation of most of java.io through java.nio moved serveral
995 runtime specific I/O methods. Most methods do have a generic default native
996 C JNI implementation in native/jni/java-nio.
997 * Runtime support methods for java.io.File have been moved to VMFile which
998 also comes with a default JNI C implementation.
999 * To support the new service provider mechanism runtimes must make sure that
1000 extension JARs are made accessible via the default context class loader.
1002 New in release 0.08 (2004/12/03)
1004 * java.util.regexp implementation through gnu.regexp wrappers.
1005 * java.net.URI implementation.

1016 favour of a new one with the same funtion but a different name.
1017 (See Deprecated Methods section in the GNU Classpath Hacking Guide.)
1018 * javax.print.attribute.standard added.
1019 * Lots of java.nio, java.net, java.io
1020 * Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+.
1022 VM Interface changes:
1023 * Split native methods in java.lang.Runtime into java.lang.VMRuntime.
1024 * Resources are now also loaded/needed through the bootstrap classloader

1036 New in release 0.07 (2003/30/11)
1038 * Works with libtool 1.5 (and 1.4.3).
1039 * java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango.
1040 Lots and lots improvements on the peers.
1041 * java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D:
1042 Subdivision and flatness calculation implemented.

1080 java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf,
1083 VM Interface changes:
1085 * VMClassLoader.loadClass(), the bootstrap classloader called by
1086 Class.forName() and ClassLoader.loadClass(), may now return null when
1087 a class is not found instead of throwing a new ClassNotFoundException.
1088 This is a performance optimization in some cases. This also changes
1089 the Class.forName() reference code.
1090 * Native methods in Class have been moved to VMClass. A few additional
1091 methods are also available in VMClass to provide optional performance
1093 * A VM can now supply its own String.intern() strategy through the
1094 VMString class. The supplied VMString reference class implements the
1095 original WeakHashMap strategy.
1096 * Float and Double to/from bits conversion functions can now be supplied by
1097 the VM through VMFloat and VMDouble. Default JNI conversion methods are
1100 New in release 0.05 (2003/02/15)
1101 * Supports free Java VMs Jikes RVM and Kissme out of the box, perhaps others.
1102 * Supports GNU Crypto 1.1 as the official provider of cryptographic primitives
1103 and tools for GNU Classpath, available separately from
1104 http://www.gnu.org/software/classpathx/crypto/crypto.html.
1105 * Supports GNU Classpath Tools sub-project of GNU Classpath, official provider
1106 of standard tools such as gjdoc, a javadoc replacement, and others. Future
1107 releases of GNU Classpath will begin to include these tools, available
1108 separately from http://www.gnu.org/software/cp-tools/.
1109 * Java primitives can be used to support AWT native threading, see
1110 the --enable-portable-native-sync configure option which may become the
1111 default in a future release.
1112 * Include file jni.h has been updated to the 1.4 specification.
1113 * VM specific internal types for jobject, jfieldID, and jmethodID are
1114 supported in jni.h. More details can be found by reading the comment
1115 in include/jni.h.in. By default the old definitions are used instead.
1116 * New VM helper class java.io.VMObjectStreamClass which should provide
1117 the hasClassInitializer() method. Previously ObjectStreamClass used
1118 Class.getDeclaredMethod("<clinit>") but according to the spec this
1119 should always throw NoSuchMethodException for class initialization methods.
1120 A JNI reference implementation is provided as
1121 vm/reference/java-io/java_io_VMObjectStreamClass.c
1122 * There have been numerous infrastructure improvements
1123 * Configure option --enable-gjdoc to generate javadoc-like output
1124 * Gjdoc output is included with distribution, see doc/api/html/
1125 * DESTDIR fully supported for install and uninstall
1126 * Runtime.execInternal contract changed to allow for null `env'
1127 and to accept `dir' argument.
1128 * VMObject.getClass() removed. It was never used.
1129 * java.lang.Throwable is now a 'normal' GNU Classpath class that uses the
1130 VM specific java.lang.VMThrowable to get at the VM state and (if needed)
1131 the StackTraceElements for a particular exception. A default implementation
1132 (that does nothing) is provided in vm/reference/java/lang/VMThrowable.java.
1133 * The vm/reference classes from the gnu.vm.stack and their counterparts
1134 ExecutionStack and StackFrame in gnu.java.lang have been removed since they
1135 are not actually part of the VM interface anyway.
1136 * The GPLed com.sun.javadoc classes have been moved to the gjdoc application
1137 from the GNU Classpath Tools project. See for more information the homepage
1138 at: <http://www.gnu.org/software/cp-tools/>.
1140 New in release 0.04 (2002/05/05)
1141 * Additional configure options to disable zip creation and installation as
1142 well as disable gtk peer native compilation.
1143 * Addition of java.nio, java.util.logging, and javax.swing.
1144 * Integration of most or all of the ORP patches to date, the purpose of
1145 which are to make it possible to use JBOSS with ORP and Classpath. This
1146 is still in a testing phase however.
1147 * Significant changes in the reference VM interface that may require
1148 support from the JVMs.
1151 New in release 0.03 (2002/02/08)
1152 * More merges with libgcj have been performed including java.math which now
1153 provides a pure Java implementation of that package.
1154 Current status at <http://gcc.gnu.org/java/libgcj-classpath-compare.html>
1155 * A pure Java implementation (Jazzlib) of java.util.zip is available.
1156 * Added the java.rmi implementation that Transvirtual donated to the FSF.
1157 * Includes jni.h now, eliminating the need to specify a particular VM
1159 * No proprietary classes or programs are required to compile.
1160 Compiles out of the box with jikes or gcj.
1161 * Separation of compiling Java source and native libraries through the
1162 configure mechanism. If given no arguments, configure will setup the
1163 subsequent build to only produce Java bytecode (.class files). More
1164 information is available in INSTALLING.
1165 * Support for compiling in a separate directory, as an example you may
1166 cd classpath-0.03; mkdir build; cd build; ../configure; make
1167 * Works with Orp 1.0.9 out of the box. Build instructions can be found at
1168 <http://www.gnu.org/software/classpath/doc/orp.html>
1169 * Lots of bugfixes that were found by using Classpath with the gcj, Orp,
1170 SableVM, KissMe and Jaos VMs. Please use our bugdatabase at
1171 <http://savannah.gnu.org/support/?group_id=85>
1172 * Lots of updates to make Classpath more compliant with the 1.2, 1.3 and 1.4
1173 API specification. The current status can be found at
1174 <http://www.gnu.org/software/classpath/status.html>
1175 * All files are now distributed under the same terms. Added clarification to
1178 New in release 0.02 (2001/01/06)
1179 * Support for printing exceptions with Japhar 0.09 + patch included in
1180 resource/japhar-0.09.patch.1.
1181 * Typos, assorted bugfixes.
1183 New in release 0.01 (2000/11/20)
1184 * More packages are included now, though many remain untested.
1185 * Support for Japhar 0.09 included.
1187 New in release 0.00 (1999/02/01)
1188 * First official development release of clean room class library for Java
1189 * Following packages included:
1193 -- java.lang.reflect
1196 -- java.security (partial and non-functioning)
1197 -- java.security.acl
1198 -- java.security.interfaces
1200 * Code is mostly Java 2 (see JDK 1.2) compatible with some functionality
1201 missing and/or untested.
1202 * Support for Japhar (http://www.japhar.org/) virtual machine is included.
1203 Requires the current Japhar from CVS.
1204 * Extensive javadoc comments for public API included
1205 * Licensed under the GNU Library General Public License (see COPYING.LIB)
1206 * Does not depend on any non-free code - developed in a "clean room"
