Therefore the test is provided in a separate repository and it needs to be discussed if the test is necessary to have inside the JFX repo and if so, how it should be integrated.

Interesting feedback.

I was told that it did work on an older version, but I don't remember if I tested it or not. Apparently MacOS changed something in their event handling logic from one version to another so that only one event handler could be registered at a time.

If JavaFX would have its own Desktop class, then the NativeEvent handler would not need to forward those events anymore, as FX would handle it.

If JavaFX would handle some events that AWT doesn't, then I guess it would make sense to also allow AWT to send native events. Since I didn't found any such events yet, I didn't look into it.

I don't understand Your last point. If no event handler is registered, JavaFX still forwards them, but they won't do anything unless a handler is registered at some point. So what exactly do You mean?

So is there something You want me to do in the code?
Or did I answer Your questions?
