1. Install JRE8 b69
2. Java dir and its shortcut items are created.
3. About Java dialog box (opens when clicked on 'About Java' item) shows Version 8
4. Install 7u5
5. Uninstall JRE8 b69.
6. About Java item now shows Version 7 Update 5
7. Uninstall 7u5
Its expected that Java shortcut items will be removed from the Start Menu after 7u5 is uninstalled since there is no jre remaining on the system.
Actually these items are still there and show shortcut item error - "javacpl.exe has been changed or moved" when clicked.
