The hwaccel mechanism in Apple's Java implementation uses 
OpenGL. Currently, if you turn hwaccel on, you will run into 
problems if you try to run gl4java at the same time. It should 
be easy to make gl4java work with hwaccel, after all, they use 
the same hardware accelerated surface, so the entire step of 
gl4java asking and pinning down its own hwaccel surface goes 
away. But it takes time, however little, to do it and right now 
I'm busy working on Java and preparing for WWDC. After all what 
good is gl4java without kick ass Java support underneath it 
right? ;-)

I will look at gl4java shortly and update it.

cheers
