FULL PRODUCT VERSION :
JRE 1.7 and JRE 1.6

ADDITIONAL OS VERSION INFORMATION :
MS Windows XP

A DESCRIPTION OF THE PROBLEM :
I have installed both JRE 1.7 update 4 and JRE 1.6 update 30. The problem is that I can not run any Java app in my browser (Chrome or Opera). Chrome says that Java is not installed (yep, I tried to reinstall - didn't work), Opera gave an error that web site is running Java 1.6 and opera tried to run with java 1.7 and it crashed. The question is why chrome and opera do not use Java 1.6 instead of that buggy 1.7 which is not backwards compatible.

 And I can not uninstall Java 1.7 because I need it to run my own application created with Eclipse using Java 1.7.



REGRESSION.  Last worked in version 6u29

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Using WIndows XP install Java 1.7 and Java 1.6. Try to run web based java application. Thats all.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Running java applet in any page.
ACTUAL -
Java applications do not work in Chrome and in Opera and Chrome doesn't recognize it has java installed.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Uninstalling JRE 1.7. But as I said before I need 1.7 to run my own application. Yes, I could have created my app using JDK 1.6 but that is not the point.
