Two possibilities -

Did you up the allocated vram ? (I think this might not be a factor on newer Raspbians, they were going to a dynamic split).

Does X11 fill the full screen when it runs  ?

It would be interesting to know what FX thinks the screen is sized at, -Dprism.verbose=true

My app is also open source, so I can share the code, but I need to fix a couple of things so it doesn't depend on Maven snapshot artifacts (also, my Hudson is in maintenance and I can't confirm the app can be compiled from the outside world). I'll alter post to oss.sonatype.org the binaries, so if someone wants to try it, just let me know.
