We also would like to integrate a JavaFX UI in an external OpenGL context.
We already do it with regular Swing by leveraging JOGL and another
OpenGL-AWT geom bridge  library in our Open source project (, but it's not so simple to to it
well. It would be greate to be able to make JavaFX to work "easily" with
other applications which also use OpenGL.

Our use case is integrating Java graphics on top of an external context
created by apps such as a flight simulator terrain rendering for example.
We could also do it in Java of course, but often you have to use an
existing OpenGL renderer for that.

However for information it's not necessary to change the JDK to do this in
Swing, even if it is not simple as I said.
