Title bars of JInternalFrame not appearing properly in GTK LookAndFeel on SolSparc10-JDS with Mustang-b77 2D PIT build (2006-03-18). To reproduce, do the following:

1. Run SwingSet2 on SolSparc10-JDS.
2. You would see some JInternalFrames on the first tab.
3. Choose GTK Look & Feel from the menu.
4. If the title bars appear transparent and if you see only the java-cup icon on the left corner of the title bars, the bug is reproduced.

This is reproducible on Cinnabar as well with the same PIT build. Not reproducible on other look & feels. Not reproducible on Mustang b-76 with GTK LAF. Hence it is a regression introduced in this PIT and must be fixed for beta2.
