Java HotSpot(TM) Client VM (build 1.4.1-rc-b19, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
sun's TechTip
http://developer.java.sun.com/developer/JDCTechTips/2001/tt1
220.html

shows how to create modal or semi-modal internal frames
using a glassPane. If a JComboBox is added to the internal
frame, the following behavior is observed:

- JDK1.3.1, JDK1.4.0/1.4.1Beta with a Look And Feel
different from "Windows": Only the portion of the combo box
list falling outside of the internal frame bounds is
visible.

- JDK1.4.0/1.4.1Beta with Window with Windows Look And
Feel: The JCombo list is visible.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the attached application (which is derived from
Sun's example) passing "Windows" as argument.
2. Click on "Open"
3. Open the combo list: everything looks ok.
4. repeat the same operation passing "CDE/Motif"
or "Metal". the list is partially invisible.

EXPECTED VERSUS ACTUAL BEHAVIOR :
The combo should work fine with all look and feels, or Sun
should provide a working tip.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER WORKAROUND :
use non-modal or non internal modal windows, but this is
really annoying.
