FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)

FULL OPERATING SYSTEM VERSION : Windows NT Version 4.0
(client)

ADDITIONAL OPERATING SYSTEMS : Microsoft Windows 2000

A DESCRIPTION OF THE PROBLEM :
After upgrading from Java Web Start 1.0.1 to 1.2, which was
installed as a result of installing 1.4.1, any existing
downloaded applications cannot be deleted with the "Remove
Application" menu selection.

However, if you add another downloaded application, then
you can delete the original downloaded applications with
the "Remove Application" menu selection.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Install JWS 1.0.1
2. Download an application (I did 2)
3. Upgrade to JWS 1.2
4. Try to "Remove Application", won't work.
5. Download another application.
6. Try to "Remove Application" to delete the original
application that wouldn't delete. Now it will delete.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I expected step 4 above to delete the old application. The
JWS application manager would not delete it until later.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
no messages, no exceptions, and the applications were not removed.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER WORKAROUND :
If you download a new application, all applications are
removable.
