What I expected.  Perhaps the crash report will eventually trickle down to somebody at Apple that can do something more.

It is a NetBeans 7.2 Swing + JavaFX project that was run from the IDE.

No.  But I haven't looked into the magic that the NB Ant script is doing for Swing + JavaFX  it even makes a main class derived from Applet for some reason.. I didn't bother to sanitize it.

Now you've got me curious too.
