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)

FULL OS VERSION :
OS: Windows XP Build 2600 Service Pack 1

A DESCRIPTION OF THE PROBLEM :
HotSpot crashes when scrolling a JScrollPane with a swing text component inside.
This only happened to me once (so far) and I was unable to reproduce it. Nevertheless it is clearly a bug. Seems to be a threading issue with AWT (again! - see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5065001).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Scroll JScrollPane repeatedly.
I was unable to reproduce it, but it is clearly a bug (see log)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Scrolls *without* crashing
ACTUAL -
JVM crash with error log.
