Hey,
I submitted a bug about a month ago to Apple. Apple engineering just responded, indicating that they thought it was not their problem, and to inform the developers of this implementation of JOGL. How do I do that?
The Java 2D / JOGL bridge is unfinished on Mac OS X. The furthest we ever got with it was an advanced prototype. Work would be needed both by Apple on their implementation of the Java 2D OpenGL pipeline, and by us on JOGL, in order to get it closer to working reliably. I would advise you to not count on this happening any time soon, but instead to figure out workarounds such as using the heavyweight GLCanvas or moving some of your Swing UI up to pure OpenGL via FengGUI or similar.
That was the problem. I am now more familiar with JOGL then when I submitted the bug report. Looking at the JOGL source code, I see the throwing of the “Not yet implemented” exception. I am a GPGPU guy, and do not even use this, but thanks. I ran this withdrawn JOGL demo, called twinkle, and am just the one who reported it.
