FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode, sharing)

(also valid against beta 1)

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

A DESCRIPTION OF THE PROBLEM :
Some GridBagLayout code that previously worked in 1.4 and earlier JDKs now throws ArrayIndexOutOfBondsExceptions. These GridBagLayouts were writting using NetBeans 3.6, so I don't think I am breaking any real bad rules.

Attached two test cases.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the two test cases attached in source code box

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
no stack traces, frame shows with some widgets
ACTUAL -
stack traces. See Error Message(s) box

CUSTOMER SUBMITTED WORKAROUND :
don't use grid bag layout. Or re-package grid bag layout from a 1.4.x JDK and re-use it.

Release Regression From : 1.4.2
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
