Extensions installed by java web start can be put in the lib/ext directory
of the jre, or put in the cache.  Java Web Start never removes them, and
dosn't keep track of what applications are using what extensions.  
It has been requested that we allow the user to selectivly delete these 
extensions, at least after removing all applications using them.

Name: nt126004			Date: 07/10/2002


FULL PRODUCT VERSION :
All versions 1.3.1 and 1.4.1 Beta

FULL OPERATING SYSTEM VERSION : Windows 2000 SP2, Windows
NT SP6, Solaris 2.8


A DESCRIPTION OF THE PROBLEM :
Currently the JSR-56 specification discusses an extension
installer that should be called when the application is
first installed or when the application is removed as
discussed in section 5.2.3 of JSR-56 V1.0.1.  Currently the
reference implementation on addresses the installation but
does not address the uninstall.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Install a JNLP enabled application
2. Open JWS console
3. Remove the application from the JWS console

EXPECTED VERSUS ACTUAL BEHAVIOR :
Currently when you remove the application from the JWS
console it removes the icons, shortcuts, and clears the
cache but does NOT call the uninstall !  When the user is
removing the application this is obviously an uninstall
otherwise the current implementation would not be cleaning
up the shortcuts and such.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER WORKAROUND :
No work around method with JWS, currently I have to provide
a JNLP application that will do the uninstall but the user
has to manually click that to clean up their machine ...
not good !
