I have been fighting with this too, recently. I switched back to the (ugly) default preloader (as that one shows up nicely) until I find some more time to investigate this.

If you enable Java Webstart full tracing

"\bin\javaws.exe" -userConfig deployment.trace true
"\bin\javaws.exe" -userConfig deployment.trace.level all

you should see preloader messages which should give you some information about what is going on. In my case I could see a lot of messages like these

preloader: Added pending event 2: DownloadEvent[type=load,loaded=0, total=62791, percent=0]

indicating that the custom preloader hasn't been verified/started yet but download events were already coming in.

What happens if you switch to ?

EDIT

This is my test JNLP. Seems like you're missing to specify the JavaFX runtime resource?
