javacpl.cpl remains in /system32 or /SysWOW64

On x64 XP, uninstalling 7u10 does not remove javacpl.cpl from the /system32 or /SysWOW64
That will leave broken java control panel in windows control panel

*** Tested Configuration:
- x64 XP(sp2)
- jre 7u10-b16

*** Steps to reproduce:
0) Uninstall all JREs from the system
1) Make sure related java registries clean
2) Install 64-bit jre 7u10-b16
3) Uninstall 64-bit jre 7u10-b16

If you see javacpl.cpl remains under /system32, the issue is reproducible. The same issue occurred with 32-bit jre as well. As the result, broken java control panel can be found under windows control panel
