Description
I am launching a test which creates a frame using different GCs available and pushes the frame into fullscreen mode. This is repeated for all GDs as well. When I run this on SuSE10 having Nvidia Geforce FX5900 with the latest Nvidia Driver - 9746, the test hangs immediately after the launch (after bringing up the first fullscreen frame). I pressed CTRL + '\' and the thread dump showed that there is a java level deadlock. I have given the thread dump below.

This is not reproducible on JDK7-b07 but reproducible on JDK7-b08. I tried on another SuSE10 machine with ATI Radeon 9600 and it was throwing a NPE (6529869). Not reproducible on Win32. 

I have attached a sample test. Launch the sample test on the above config and you would notice that the test hangs immediately after the launch.

Here is the thread-dump:

Comments
EVALUATION Fixed as suggested...

EVALUATION Likely caused by the fix for: 6205557: Changes to image data should be tracked at a finer granularity which went into b08. The problem is that X11GraphicsDevice.getProxyKeyFor() is a synchronized method (that synchronizes on the device instance). We've found in the past that synchronizing on an X11GraphicsDevice/Config instance can be dangerous as it's prone to deadlocks and other issues (see 6299808, for one example). In this case, there's no reason to synchronize on the device instance; an easy fix would be to instead synchronize on the x11ProxyKepMap itself. I'll let the RE for 6205557 make the final call though...
