OpenJFX on iOS using RoboVM

Wed May 22 05:55:58 PDT 2013

Tom, could it be due to some class missing? Do you get an exception? If you
launch the app with the -rvm:log=warn option failing Class.forName() calls
will be logged.

RoboVM strips out classes not being referenced to keep down the size of the
app. The compiler has to be told about classes that get loaded using
reflection. That's what the -roots command line option and the <roots>
section in the robovm.xml file are for. You may have to add a <root> there
for the class(es) containing the effect code. Or you could just add
<root>**.*</root> and RoboVM will compile and link in everything.
