FULL PRODUCT VERSION :
  Today is 2002-11-18.
I downloaded the latest j2sdk1.4.1_01 a few days ago and removed it immediately
because it was crashing and I could not run my application that runs well under
j2sdk1.3.1

I did not get it because I removed the latest version of
j2sdk1.4.1_01 immediately due to frequent errors, and
reinstalled the j2sdk1.3.1


A DESCRIPTION OF THE PROBLEM :
I use more than one JList to select some information. As
soon as I start flipping between them I get errors that I
pasted below.

REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create two JTextFields (to display selected info)
2. create JButton to refresh JLists (clear and reload)
3. create two JList
4. load information into JList a
5. load information into JList b
6. select info from JList a
7. select info from JList b
8. start flipping between them or press refresh button

EXPECTED VERSUS ACTUAL BEHAVIOR :
when I press the JButton the JList should get cleared and
info reloaded without the JButton getting stuck.

when I select info from JList it should be displayed
without crashing (below).
