Javafx Won't run on Mac OSX

I have a customer trying to run a javafx app on Mac OS X 10.8

Launching is fatal - with:
Exception in thread "main" java.lang.UnsupportedOperationException: Unknown is not supported
at com.sun.javafx.tk.Toolkit.getDefaultToolkit(Toolkit.java:139)
at com.sun.javafx.tk.Toolkit.getToolkit(Toolkit.java:194)

at com.sun.javafx.application.LauncherImpl$1.run(LauncherImpl.java:115)
at java.lang.Thread.run(Thread.java:722)


He is using java:
java version "1.7.0_11"
Java(TM) SE Runtime Environment (build 1.7.0_11-b21)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)


On a related?, note, before this fatal error happens, we also get errors from log4j:

Did Oracle release a Java VM that is so broken on Mac that it can't determine what platform it is?

Any workarounds available?
