A DESCRIPTION OF THE REGRESSION :

In a textfield, under certain circumstances i like to change the background color to GREEN. And when the circumstances are not true anymore, I would like to restore the color back to what it was at the beginning ( ie default ).
I can set the color to what looks like green. BUT i cannot restore the color back to the original background color. Its close, but does not match.

REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
/* run program. hit green button. hit default button.
 * BTW if you change the AWT_TOOLKIT=MToolkit environement setting it behaves

RELEASE LAST WORKED:
5.0

RELEASE TEST FAILS:
mustang-b70

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
i expected the background color to be restored.
ACTUAL -
When default background color is restored, its just not the same as when the textfield was first created.

OBSERVED APPLICATION IMPACT:
probably not much impact. After all such differences in background color have already been relegated to the "will not be fixed" category of bug and conformal standards, much to the fustration of developers.
