Thanks for the info. I'm assuming your application uses full screen mode, since the d3d pipeline is disabled in 6u4 by default in windowed mode.
It's hard to tell why exactly the initialization would fail, but like I said it would typically happen when application dies during the d3d pipeline initialization phase. We set a flag to 0 in the registry before trying to initialize Direct3D device, then we initialize it and perform some tests, and if the check is successful we set the registry value to 2. If vm starts up and detects that the registry value is 0 it assumes that the vm which tried to initialize d3d crashed and never had a chance to set it to 2, so it doesn't even try to init d3d. This was done to work around some very bad driver bugs which would send a system into continuous reboot cycle (incidentally, with older ATI video adapters). Now, there's an obvious problem with this approach - if two applications start at the same time and the timing is right it's possible that one of them will read value 0 set by another app and won't init d3d. May be that's what's happening in your case. Anyway, there's a flag you can specify which will force the pipeline to re-run the test on startup. Use it at your discretion (not a supported flag, could go away in the future release, etc). The flag is: -Dsun.java2d.accelReset=true You can, for example, run a small java app at system startup time with this flag to make sure the flag is reset at least once during user's session. Or if you're confident that you won't run into issues in your controlled environment you can always run your apps with it. One other thing - I would suggest to try the beta builds of upcoming 6u10 release (http://jdk6.dev.java.net) to see if you have any issues with it on your systems. It has a new d3d pipeline (which may or may not be enabled on your hardware).
