To use the gem5 java jar, you will need to load the corresponding .so.
```shell
-System.loadLibrary("gem5OpJni");
+System.loadLibrary("gem5Ops");
```
In your java source, import the gem5Op class which will have methods for
calling each of the gem5 operations.
```shell
-import jni.gem5Op
+import gem5.Ops
```
These methods will all use the magic instruction based trigger mechanism.
