Triggering thru. DT (via http://java.com/js/dtjava.js), after installing the 7u2 co-bundle (jre + fx), the JavaFX runtime download and installation occurred again.
 Users end up with the situation " You already had the version of JavaFX installed......"

*** Steps to reproduce:
0) System does not have JRE (or < JRE 1.6.0) and JavaFX 2.0_ runtime
1) Invoke a JavaFX application via dtjava.embed or dtjava.launch
(e.g. http://sqeweb.us.oracle.com/deployment1/dtfx/dtjavaEmbed.html)
where platform is defined as:
{ jvm: '1.6.0_10+',
  javafx: '2.0+'
}

If you see the following behavior, then the issue is reproducible:
- The latest public JRE 7u2 will be installed along with JavaFX 2.0.2 runtime (as part of the 7u2 co-bundle)
- And then, dtjava.install will try to download and install JavaFX as part of the missing component in the original check.

Users will see the JavaFX runtime to download the second time and end up with the situation " You already had the version of JavaFX installed......"

The same scenario can be reproducible using dtjava.launch as well
