Glaring JavaFx Problem
The concept that JavaFx cannot be embedded into an existing Swing application baffles the mind. There were hacks to do this in 1.1, and I have it working in 1.2 (minus mouse events), but to not support this in the official API is one of the strangest things I’ve seen. This would be the #1 way to drive adoption of JavaFx, yet Sun seems to be blind to this fact. There are plenty of Swing apps that could be enhanced to have some nice eye-candy charts, etc.
