Latest 6ux users run into the issue when trying to invoke the JavaFX applets that requires jre 1.6+ and fx 2.1+

* Scenario:
- Users have latest 6ux JRE and DT native plug-in
- Invoke the javafx applets that require jre 1.6+ and fx 2.1+
(note that the latest dtjava.js included in the test applet)

* Expected behavior:
- DT will serve the latest standalone javafx runtime publicly available


* Actual behavior:
 - FF, GC: Follow the DT flow will lead to Deployment Toolkit Error: Deployment Toolkit cannot install the requested version
- IE: Routing to java.com manual download page


*** Steps to reproduce:
0) Uninstall all JREs, DT native plug-in, JavaFX runtime from the test system
1) Install the latest 6ux (e.gL 6u33 or upcoming 6u34)
2) Use Firefox or Chrome to invoke the JavaFX applet that requires jre 1.6+ and fx 2.1+

(note that: the latest dtjava.js deployed in the above test applet)

3) Click "Free Download" button

If you see the Deployment Toolkit Error dialog, then the issue is reproducible. If IE is used, users getting routed to the manual jre download page from java.com

The same issue occurred for applets that require jre 1.6*/fx2.1+, jre 1.6+/fx2.0+, jre 1.6*/fx 2.0+
