Uninstalling JDK, does not delete and clean the JDK install folder.

Steps :
1) Install JDK6u10-b26 (PIT) build. It gets installed properly.
2) Check for the installed folder, don;t copy anything in any of the folders.
3) Uninstall back the JDK.

If the jdk1.6.0_10 folder is not getting deleted, this bug is reproduced.

For the detailed left over jdk folder structure, see the attachment file.
 - jdk1.6.0_10
     - demo
     - jre
     - lib
     - sample
Subrata meant install JDK.

so this is basically installing and uninstalling JDK.
I just verified it on windows XP.

This is a regression from 6u10 build 25 promoted.
