A DESCRIPTION OF THE PROBLEM :
Implementing JToggleButton. When toggle button is pressed, the background color setting is ignored. Currently, it only appears to be respected when the button is in the up (non-selected) position. I have attempted to override EVERY option in the UIManager UIDefaults which pertains to "ToggleButton" color properties to override this behavior without success. I have noticed that this has supposedly been a problem since after JDK1.2 and that bugs of a similar nature have been closed and indicated as fixed.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Simply extending JToggleButton and placing within a JFrame. Set the background color to a desired color. Press toggle button. Color is ignored when selected. Depress toggle button (deselected), color setting is respected.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
In this case, the background should always be yellow whether the button is pressed or not. Not my main goal, but I did this approach simply to show that the color is ignored when the button is selected.
ACTUAL -
unknown default background color shown when button selected.

REPRODUCIBILITY :
This bug can be reproduced always.
