Duplicate shortcuts created when the cache dir is changed

Tested build : mustang b59g
Tested OS : Solaris 10 JDS

1. Install mustang build 59g
2. Enable user cache
3. Set Java Control Panel->Shortcut Creation->Prompt User
4. Launch any application (notepad from java.sun.com) and the application will ask whether you want to create a shortcut
5. click yes
the shortcut is created in the desktop and the menu
6. change the cache directory to some other directory
7. launch the notepad appln using the shortcut created above
The application asks for the permission to create a shortcut on desktop and the menu
8. click yes
Now 2 shortcuts got created with the name on both the desktop and the menu

Expected Behavior : There should be only one shortcut at any point of time
Tried log out and log in again. Those 2 shortcuts still exist and able to launch the application using both the shortcuts
Note : The above behavior is not seen on windows.
