Thanks Scott for your fast answer.
Well, in this case PlatformImpl.runLater(new Runnable() { @Override public void run() { ... is never called. I believe it is not called because the Stage is not running anymore and therefore the JFX Main Thread is stopped. I am now on 1.8.0_60 and have still the same behaviour :( regards Matthias > Am 18.05.2015 um 14:17 schrieb Scott Palmer <swpal...@gmail.com>: > > I would have thought that #2 was correct.
