I tried to use bigger memory: -Xms1500M -Xmx1600M
Sometimes the jogl program runs ok. sometimes it crashs, cometimes it throws exception:

Exception in thread “Thread-41” Exception in thread “AWT-EventQueue-0” javax.media.opengl.GLException: Error making context current: 0

I am using vista with a dual core cpu and x1300 video card

i think your problem is somewhere else besides your GL panel.

What is the line in YOUR program that generates this? that is what is the package name for your java files.

Also looks like you are trying to use too much memory. I think there is an upper limit on how much JVM can allocate. Also could have something to do with how much total RAM your box has, and how much of it is free at the time you start your program.

I am using two 1G RAM which means I have 2G RAM. Can Java use memory up to 1.5G?

The problem is we cannot located the line which causes the crash and throws the exception. The exception only shows the stacks from JOGL. So I wonder If other guys had ever met such problems.
