FULL PRODUCT VERSION :
JDK 1.5.0_12, also broken with JDK 6 (update 1, 2, 3 and 4)

ADDITIONAL OS VERSION INFORMATION :
Windows XP Service Pack 2


A DESCRIPTION OF THE PROBLEM :
The problem is that when the Windows Theme is set to "Windows XP"
several fields, Chunk Size, Ping Interval and Drives To Crawl field boxes
are corrupted or truncated.

When the Windows Theme is changed to "Windows Classic" the  fields,
1, 2 and 3 are displayed correctly.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compiling the pasted-in class below and noticed that when you run it with Display Properties /Appearance / Windows_And_Buttons style set to Windows Classic, the UI looks good, when you run it with Windows XP, the UI looks all squished.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You will have to run it and see the difference between Classic and XP style.

REPRODUCIBILITY :
This bug can be reproduced always.
