A DESCRIPTION OF THE PROBLEM :
On Linux, setting the background color of a Panel incorrectly changes the background color of buttons contained in the panel, often making their text unreadable.

This error does not occur on Windows.

Compile and following program wit:

javac ButtonTest.java

java ButtonTest

EXPECTED VERSUS ACTUAL BEHAVIOR :

Button shows up black-on-black. Compare with behavior on Windows which does *not* change the background color of the buttons to match the panel.

REPRODUCIBILITY :
This bug can be reproduced always.
