JavaFX UI hangs

I am writing a JavaFX program under ecilpse, It works well on my local machine i.e., I can execute the runable jar after I export. However, when I put the executable jar to another machine, the UI was not responding. Here are the codes I launch the javaFX program.

 @Override
       public void start(Stage primaryStage) {
        primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
           @Override
           public void handle(WindowEvent e) {
              Platform.exit();
              System.exit(0);
           }
        });
           this.primaryStage = primaryStage;
           this.primaryStage.setTitle("Server Simulator");
           context = new ClassPathXmlApplicationContext("classpath:PrTrSim.xml");
           this.displayQueue = (LinkedBlockingQueue<Message>) context.getBean("displayQueue");
           this.userInputQueue = (LinkedBlockingQueue<Message>) context.getBean("userInputQueue");
           this.outgoingQueue = (LinkedBlockingQueue<Message>) context.getBean("outgoingQueue");
           this.incomingQueue = (LinkedBlockingQueue<Message>) context.getBean("incomingQueue");
           addQueue.add(this.displayQueue);
           addQueue.add(this.outgoingQueue);
           addQueue.add(this.incomingQueue);
           initRootLayout();
           showSimOverview();
       }

   public static void main(String[] args) {  
        launch(args);
    }

The PrTrSim.xml is for initialization of two components(messageProcessor and SocketIO reader) which are running behind.The 4 blocking queues are for message receiving and handling.

To avoid blocking of the main thread you should use the JavaFX concept of tasks or services as explained in details here: http://docs.oracle.com/javafx/2/threads/jfxpub-threads.htm
