6u10-b10 PIT build is broken on Windows Vista and launching any UI application causes a VM crash. Build works fine on WinXP. I am able to reproduce this on all Windows Vista versions.

Here is the stacktrace of SwingSet2 Crash:

The same crash can be reproduced with any UI application.

This is a blocker for the PIT on Vista and b10 is a beta candidate build.
