Adding NVIDIA 'Threaded optimization' workaround/fix at initialization on Windows for javaws/applets.
It has been observed that for some combinations, eg:
- Windows 7 64bit (other variants may apply too)
- NVIDIA 8600M GT
- 260.99
the NVIDIA setting of 'Threaded optimization' := 'auto' (default) causes the JVM to simply crash
in case of javaws and [jnlp] applets.
'Threaded Optimization' := 'off' works reliable
'Threaded Optimization' := 'on' never works with javaws and applets on the above configuration
A user could workaround this by setting 'Threaded Optimization' := 'off',
however, this would disable many users on the spot,
since you cannot ask the average user for such a task, if she only wants to see a web page.
This patch 'fixes' the 'auto' mode by running the eager GL profile initialization
within a block of single CPU affinity:
SetProcessAffinityMask(pid, 1);
try {
initProfilesForDeviceImpl(device);
} finally {
SetProcessAffinityMask(pid, sysValue);
}
Hopefully we can remove this hack with a driver fix.
However this workaround is as little invasive as possible.
