JavaFX port to iOS/Android status

Niklas, this is *awesome* work, thanks very much on behalf of the JavaFX

It is very promising that so few changes were required to get things
working.  One thing I noticed in the video was that BrickBreaker animation
performance was a bit choppy i.e. not smooth.  Is this a symptom of the
video itself or does JavaFX run like this on iOS?

Of course I realise that it's only *very* early days so I am sure
performance issues can be improved with prudent optimisation.  I am just
curious to know whether the video gives an accurate picture of what's really

Anyway, this is the best news I have had in ages!  Keep up the great work!

I'm the founder of the RoboVM project. Yes, RoboVM uses AOT and yes that's a
real iPad in the video.
