Hi Tamara,

It's been a long time since I worked on gl4java so I'm affraid I can't
really help you out with the bug you've encountered. I just wanted to
reinforce Ken's statement on switching to jogl. As far as I know jogl
still doesn't support calls to glMakeCurrent. What it does support and has
for some time now is manual control of the buffer swap. Maybe this is
sufficient for what you're trying to do?
