I'd like to use JavaFX to create top level netbeans components and run the resulting application on RedHat Enterprise Linux 6. It currently crashes. Is this a bug? If Redhat is not supported, what are the plans to do so?

Details:
My Netbeans Platform 7.2/JavaFX applications work correctly on Ubuntu 10.04. They crash on Red Hat Enterprise Linux Workstation release 6.3 (Santiago). The error message is:
