FULL PRODUCT VERSION :

Java(TM) SE Runtime Environment (build 1.6.0-beta2-b79)
Java HotSpot(TM) Client VM (build 1.6.0-beta2-b79, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
When using the Windows Look and Feel under XP's "Silver" theme, tool bar buttons have the wrong background color. They show up in the wrong shade of gray and look terrible.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Steps to reproduce:
1) Go to the Windows Display Control Panel and hit the "Appearance" tab.
2) Under "Color Scheme" choose "Silver" (Blue and Olive work fine.)
3) Hit OK.
4) Launch the test program.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The tool bar buttons should have the same background as the toolbar.

ACTUAL -
The toolbar buttons are drawn in a slightly darker shade of gray.


REPRODUCIBILITY :
This bug can be reproduced always.
