The source for starting the FX-Application an handling the exit and close events looks like this:

-------------------------------------------------------------------------------------------------------------------------------------------------------

    private final Semaphore sem = new Semaphore(0);
    SwingUtilities.invokeLater(new Runnable() {
    
        @Override
        public void run() {
            new JFXPanel(); // initializes JavaFX environment
            Platform.runLater(new Runnable() {
    
                @Override
                public void run() {
                    Stage stage = new Stage();
                    stage.setTitle(moduleInfo.getDisplayName());
            
                    stage.setOnCloseRequest(new EventHandler<WindowEvent>() {
            
                        @Override
                        public void handle(WindowEvent arg0) {
                            sem.release();
                        }
                    });
            
                    stage.setOnHiding(new EventHandler<WindowEvent>() {
            
                        @Override
                        public void handle(WindowEvent arg0) {
                            sem.release();
                        }
                    });
            
                    MainFXApplication mainAppWindow = new MainFXApplication();
                    try {
                        mainAppWindow.start(stage, getContext());
                    } catch (Exception ex) {
                        LOGGER.error("Exception while fx ", ex);
                    }
                }
            });
        }
    });
    
    // Thread waits here until the semaphore gets released
    sem.acquire();
