JDK-2164063	6-pool	Peter Zhelezniakov	P3	Closed	Won't Fix

FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Linux linux 2.6.16.27-0.6-smp #1 SMP Wed Dec 13 09:34:50 UTC 2006 i686 i686 i386 GNU/Linux

EXTRA RELEVANT SYSTEM CONFIGURATION :
This also happens on Windows.

A DESCRIPTION OF THE PROBLEM :
In the example program, GroupLayout from Java 6.0 uses 100% after the window is being maximized. Also, 2 labels are not being drawn correctly.

The bug does not occur, if you use JDK 5.0 with swing-layout extension.

The example was designed using NetBeans 5.5.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the example program
Maximize the window

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Labels should be drawn correctly, CPU should be 0% after resize.
ACTUAL -
2 labels are drawn wrong, CPU stays at 100%.

REPRODUCIBILITY :
This bug can be reproduced always.
