Steps to reproduce:

Using WinXP Pro or Win2000

1) Install a recent 1.3.1 jdk to default directory.

2) Install jdk 1.4.2_05b01 to default directory.

3) Remove 1.3.1 jdk & jre using add/remove programs.

4) Open internet explorer and go to http://sqeweb.sfbay.sun.com/deployment1/mantis_ws_plugin/doc/proc/JPI_bat.html#TestCases.

Click on any of the test cases eg: 1.4.2, and the applet fails to load which is not the expected behaviour.

Registry Changes:

When 1.3.1_12 is removed the following registry keys are removed.
A snapshot of the registry before and after step 3 from above shows the following keys
being taken out of registry.

This is reproducable on both WinXP Pro and Win2000 but not on Win2003.
It is only reproducable on internet explorer but not netscape.
