You're probably right.
I've tried (on Linux) various methods to get them to work, but without success.
I hope that at least Windows users will enjoy them.
In fact, I've tried this in the recent past with other JavaFX- and Swing-based applications, also without success.
While searching for solutions on Google, I found various opinions stating that the two aren’t exactly the best of friends (at least on Linux).
For one of the applications I needed, I had to convert everything to Java3D, a task that wasn’t exactly easy.
The result wasn’t great, but it was enough for me to understand what I needed.
