FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
If you have selected the last item in a JList (in
SINGLE_SELECTION_MODE) and then remove one of the previous
items, then when you select one of the other remaining
items in the list, the last item is not repainted. It looks
as if it is still selected even though it is not. When a
repaint of that cell is forced (through minmizing or
resizing for example) then it repaints correctly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run sample code
2. Select last item
3. Press delete button
4. Select one of the other remaining items
5. Resize or select last item to force repaint

EXPECTED VERSUS ACTUAL BEHAVIOR :
I would expect the last item to get repainted as not being
selected at step 4. It should not have to wait for a
repaint to be forced.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER WORKAROUND :
Create a ListSelectionListener that does a repaint in it's
valueChanged() method every time it gets a
ListSelectionEvent.
