As stated in JOGL release information, JOGL development will shift completely to implementing the JSR-231 APIs. I plan to move Xith3D JOGL renderer to new JSR-231 APIs (i.e. change to javax.media.opengl package prefix. So, the questions are:
Will JSR-231 implementation continue under JOGL project or moved to another one?
Is it possible to access sources of new APIs [I just updated from JOGL CVS HEAD, there are some empty folders under classes, but not more]?
It has been going on under the JOGL project and will continue to. At this point we are very close to an initial release of the new APIs. We have an expert group conference call next Monday and I expect to be able to publish initial jars and javadoc soon afterward; I expect that the APIs will be mostly stable after that point although some changes will probably still happen.
cvs co -r JSR-231 -P jogl jogl-demos
Assuming you have CVSROOT set appropriately. If not,
cvs -d :pserver:guest@cvs.dev.java.net:/cvs co -r JSR-231 -P jogl jogl-demos
There have been some issues reported on certain Mac powerbooks but overall the new implementation is more robust than the previous JOGL 1.1.1. The internals have changed drastically to support the new GLContext and GLDrawable APIs but the high-level callback-based APIs (now GLAutoDrawable and GLEventListener) behave the same as before.
