OutOfMemory?

Hi all

I’m profiling my application to check out memory usage, and memory consumption seems to stay well below the max heap size (80% of the max heap size). However, occasionaly, I get this:

Exception in thread “AWT-EventQueue-0” javax.media.opengl.GLException: java.lang.OutOfMemoryError: Java heap space
at javax.media.opengl.Threading.invokeOnOpenGLThread(Threading.java:268)
at javax.media.opengl.GLCanvas.maybeDoSingleThreadedWorkaround(GLCanvas.java:245)

When this happens, the whole application freezes. The strange thing about it is that even if I clear the memory used (using the profiler), the application still stays frozen.

Has anyone came up to this problem? I use a nightly build of JSR231-beta03, built in early March.

Please post the code for your paint() method (gr.talent.viewer3d.Viewer3D$4.paint) and you’ll get more help. Without seeing the code, we can’t tell what could be causing the problem.

Cheers,

There is nothing much there, just a simple call to repaint the GLCanvas I’m using


	public void paint(Graphics g) {
		canvas.repaint();
	}
