Hello Sven,
The Processing project (
http://processing.org/) is moving to JOGL 2! I'm currently developing the new OpenGL renderer in Processing, and am using JOGL 2 rc2. I tried to update to rc3 a few weeks ago, but I encountered some problems (the context initialization would crash, while it worked fine with rc2). I'm sure that I overlooked some recent change in JOGL, but now got quite busy with some heavy refactoring in the Processing renderer itself. I will give the update another try in the coming weeks, and will let you know if I find problems.
Thanks for your great work!
Andres
