Confused about status of JFX+JRE cobundling

short answer - try 7u6 (

longer version:
    * Staring 7u4 JDK for Mac included JavaFX SDK as "true" cobundle
       (i.e. one where JavaFX files are part of same bundle and there is 
no separate installer)
    * Starting JRE/JDK 7u6 JavaFX will be shipped as true cobundle on 
all platforms
       (JavaFX platforms, i.e. no Solaris).

And "true" cobundle means:
    * there is one installer to install JRE
    * it will installs set of core JRE and JavaFX files into the same folder
    * There will be one entry in the Program Files for JRE
    * JavaFX files are subject to autoupdate as part of JRE installation
(same is true for JDK and JavaFX SDK)

    * JavaFX is not official part of the Java platform yet (i.e. JavaFX 
APIs are not part of Java specification).
      This is what was planned to happen for Java 8
    * In 7u6 JavaFX will not be automatically added to classpath 
(neither for javac not java launcher).
    * There still will be standalone JavaFX installer for JavaFX 2.2 - 
it is only intended to be used with JRE 6 and only for windows.
      No cobundle for Java 6.

hope this helps,
