FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Windows 2000 Professional

A DESCRIPTION OF THE PROBLEM :
If you set a JTabbedPane to be Opaque(true)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a JTabbedPane and add a couple JPanels
2. setOpaque(true)
3. setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT)
4. setBackground(Color.red)

EXPECTED VERSUS ACTUAL BEHAVIOR :
If you do not use SCROLL_TAB_LAYOUT, the background of the
JTabbedPane (behind the tabs) turns the red color. If you
do use it, you get a strange line under the selected tab
and the background stays the system default color. If you
shrink the window enough to force the tab arrows to appear,
the correct background color appears behind the arrows, but
still not the pane.

REPRODUCIBILITY :
This bug can be reproduced always.
