Feature is broken again from nightly build-Feb01.
Steps to reproduce
----------------
1) Install latest PIT-08 bundles
2) Set permissions to all inside .java.policy
3) Run following applet using singlejar.jar with version 0.0.0.1

 Run following applet using same jar i.e. singlejar.jar with version 0.0.0.2
http://sqeweb.sfbay.sun.com/deployment2/jitu/plug-bug/cachingtest/new/TestSJ_Carchversion.html
5)Make sure that output on Java console should display information about jar versioning.
6) Invoke Java control panel and view the files under Jar cache viewer as follows
Java Control Panel > View > Resources
There should be 2 enteries against singlejar.jar with different versions
If not then bug is reproduced
Switch to old Plug-in using JCP and everything will work fine
This is a regression of 6632521.
