FULL PRODUCT VERSION :
java version "1.6.0-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-ea-b39)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b39, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
When you set a JTextArea to RIGHT_TO_LEFT and setLineWrap to true, then add this text area to a JPanel the entire panel gets blanked out.

But if you don't have lineWrap set it is displayed correctly.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Using the code snippet below just run testLineWrap() you will get 4 successive dialogs showing the different combinations of orientation and lineWrap, and the last dialog which sets the orientation to RIGHT_TO_LEFT and sets the LineWrap true will be a blank dialog.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You should get 4 dialogs showing all 3 components.

first dialog titled "LtoR No Line Wrap"
"Test Label" [Hello There ] TestButton

second dialog titled "LtoR Line Wrap"
"Test Label" [Hello There ] TestButton

third dialog titled "RtoL No Line Wrap"
TestButton [ Hello There] "Test Label"

forth dialog titled "RtoL Line Wrap"
TestButton [ Hello There] "Test Label"

ACTUAL -
first dialog titled "LtoR No Line Wrap"
"Test Label" [Hello There ] TestButton

second dialog titled "LtoR Line Wrap"
"Test Label" [Hello There ] TestButton

third dialog titled "RtoL No Line Wrap"
TestButton [ Hello There] "Test Label"

forth dialog titled "RtoL Line Wrap"
<BLANK>


REPRODUCIBILITY :
This bug can be reproduced always.

JLabel label = new JLabel("Test Label");
label.setComponentOrientation(orientation);

JButton button = new JButton("Test Button");
button.setComponentOrientation(orientation);

JPanel panel = new JPanel();
panel.setLayout(new FlowLayout());
panel.setComponentOrientation(orientation);
panel.add(label);
panel.add(widget);
panel.add(button);

JDialog dialog = new JDialog((Frame)null, title, true);
