Mixing JavaFX with Swing in different windows

[Jeff Martin]

I saw that go by last week - though now that I think of it, it seems like it shouldn't be an Application instance method - since my app uses JFXPanel, not Application.

I also just realized that I do have a case of bringing up a javafx Stage after some Swing stuff has already happened, which I managed to fix by simply creating a bogus JFXPanel.

I would rather run the FX content in a real FX stage.  I am fine having one window be run on the FX thread and one on the Swing thread with me being responsible for synchronization via invokeLater calls.  I'm wondering if there is any magic init-mojo required.
