Fullscreen suite DisplayModeTest failing when switching from some 8-bit to 32-bit modes on WinXP. The testcase will fail with Hotspot error.

Not all mode switches from 8-bit to 32-bit will result in testcase failure, however some specific mode switches will always generate the testcase failure (Hotspot error).

- This failure was found during Mustang beta milestone testing
- The bug was introduced in Mustang build B62
- Disabling D3D with -Dsun.java2d.d3d=false has no effect on the failure
- Attaching testcase to this bug report (with Hotspot error log)

- Filing the bug as high priority as it is a Mustang regression (from 1.5 release)

Test Configuration
==================
- WinXP with Nvidia GeForce4 Ti 4800 SE
- Default resolution: 1280 x 1024, 32-bit, 60 Hertz (LCD Display with DVI)

Steps to reproduce (for always reproducible failure)
==================
- On WinXP, set JAVA_HOME to Mustang build B62 or later
- Compile and run the java sources
%JAVA_HOME%\bin\java DisplayModeTest

1) After testcase launches switch to display mode: 1024 x 768, 8- bit, 60 Hertz
2) Then switch back to default mode: 1280 x 1024, 32-bit, 60 Hertz

- The Hotspot error should occur at this time.
