App hang and pulse logger stops

[Jeff Martin]

I think I ran into this a bit when I had a mixed swing/javafx application. It was always due to inadvertently performing Swing activity while still in the JFX thread or visa versa. I think sometimes checking the stack frame on both threads would show me where it was (but sometimes not). I think I was always able to solve it with the right SwingUtilities.invokeLater() or Platform.runLater().

My apologies if you already knew all this (and for the fact that it wasn’t really helpful). I’ve heard mention on this list that there is a new “single event thread” setting for JFX 8. I’ve wondered if that would have magically solved this issue, and allowed one to remove the runLater() calls.
