Hi,

On servers running Suse 11 I'm experiencing hangups in sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) when connecting via Citrix (and setting DISPLAY to localhost:11.0). Running exactly the same code in exactly the same environment, excepth through Exceed (with DISPLAY set to my workstation's IP) it runs like clockwork.

• The error is not intermittent, it happens every time
• Reinstalling the OS does not help
• Can not reproduce it on Suse 10

This is what the main thread stack looks like:

Has anyone experienced something similar? Could this be a problem in Suse 11's display handling?

I'm thankful for any input at this point - I'm fresh out of ideas :)
