With the latest JRE 7u7 (including JavaFX runtime 2.2.1), the public JavaFX 2 Ensemble sample showcase app does not work on Mac OS X 10.8.x/ Safari 6.x

*** Tested Environment:
- x64 Mac OS X 10.8.x
- Safari 6.x
- Latest public jre 7u7 and JavaFX 2 sample showcase

*** Steps to reprocude:
1) Install jre 7u7 from java.com
http://java.com
2) Check to make sure jre 7u7 installed and functioned properly
3) Use Safari 6.x browser to load the Ensemble sample from the JavaFX 2 sample showcase page:

If the Ensemble app fails to load, the issue is reproducible. The same app works fine using Firefox on the same machine, same test conditions
