A DESCRIPTION OF THE PROBLEM :
The problem is quite simple and is a CHANGE in behaviour
from J2SE 1.3.x/1.2.x..

Using setOpaque(false) on JTabbedPane has no effect, Our
company have several applications with background images in
windows (content-panes in JFrames) and these are not
visible through the tabpanes when using J2SE1.4 (and this
has alwasys been the case since the first beta release)

REGRESSION.  Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Open a JFrame add a JTabbedpane to the center of it
2. Set a background image or color on the frame
3. Call setOpaque(false) on the tabpane
4. Show the frame and watch!

EXPECTED VERSUS ACTUAL BEHAVIOR :
The tabpane is opqaued ignoring the argument given in
setOpaque()...

ERROR MESSAGES/STACK TRACES THAT OCCUR :
None..

This bug can be reproduced always.

CUSTOMER WORKAROUND :
No workaround

Release Regression From : 1.3.1_02

bug was knwon to work. Since then there has been a regression.
