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.
