-----------------------------

    Release Notes Text: 

1. If you uninstall the JBDS Product Feature, and perform a warm restart when prompted, you will see the 'Application "" could not be found in the registry.'. 

On subsequent cold restarts, you will be able to start Eclipse, but Help > About and Help > Welcome will be corrupt.

2. If Eclipse is still unusable after as noted above, simply copy eclipse.ini_BEFORE_JBDS to eclipse.ini and restart Eclipse.

> Also need to know what happens if there are two -product directives... can we just
