The current patch I have:
http://cr.openjdk.java.net/~ddehaven/8004547/webrev.2/

Minor change to accommodate this in FX LauncherImpl (needs a new JIRA issue?):
http://cr.openjdk.java.net/~ddehaven/javafx/RT-26751/webrev.2/

This was all working fine when I left for vacation, I'm still in the process of building/testing everything and will submit a JPRT run as soon as possible.

I had commented out two tests, but FX is in sync with JDK *and* they'll pass vacuously until FX is on the ext classpath anyways so I don't think that's necessary.
