One thing that is a little confusing...in the quote in your post ronjor it states that there are security enhancements in this JRE release but on the website it also says (under the bug fixes section):

This feature release does not contain any new fixes for security vulnerabilities to its previous release, Java SE 6 Update 13. Users who have Java SE 6 Update 13 have the latest security fixes and do not need to upgrade to this release to be current on security fixes.

Found this.

Blacklist Jar Feature

Support for blacklisting signed jar files has been added to 6u14. A blacklist is a list of signed jars that contain serious security vulnerabilities that can be exploited by untrusted applets or applications. A system-wide blacklist will be distributed with each JRE release. Java Plugin and Web Start will consult this blacklist and refuse to load any class or resource contained in a jar file that's on the blacklist. By default, blacklist checking is enabled. The deployment.security.blacklist.check deployment configuration property can be used to toggle this behavior.
