Removing jre 6ux makes IE to use the old 7u2 plug-in by default

System has both;
- latest jre 6u29 installed
- jre 7u2 installed

If uninstall jre 6u29, the IE will use the old java plug-in (of 7u2) by default

*** Test configurations:
- x86 XP, win7
- IE 8

*** Steps to reproduce:
0) Make sure no jre or javafx runtime on the system
1) Install jre 6u29
2) Install jre 7u2 (latest b13)
3) Use IE to invoke any java applet to ensure the 7u2 new java plug-in being used
4) Uninstall jre 6u29
5) Use IE to invoke any java applet.

If you see the old/deprecated 7u2 java plug-in is used, then the issue is reproducible
