How to keep java from updating
Nevertheless if you would like to continue to have both versions, JRE 6 and JRE 7 can be installed on the same computer.Oracle strives to make new versions of Java backward compatible with earlier versions and the vast majority of Java applications written for older versions of Java will work –without any change- on newer versions of the JRE. Any change in the code –even if only to fix a security vulnerability- has the potential to cause an application to stop working properly.
To achieve this goal Windows users that rely on Java’s auto-update mechanism will have their JRE 6 replaced with JRE 7.
In December 2012 Oracle will start to auto-update a sample of users from JRE 6 to JRE 7 to evaluate the auto-update mechanism, user experience and seamless migration.
