JavaFX UI挂起

Question

我正在ecilpse下编写一个JavaFX程序，它在我的本地机器上运行良好，即我可以在导出后执行可运行的jar。但是，当我将可执行jar放到另一台机器上时，UI没有响应。以下是我启动javaFX程序的代码。

 @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);
    }

PrTrSim.xml用于初始化后面运行的两个组件（messageProcessor和SocketIO reader）.4个阻塞队列用于消息接收和处理。

为避免阻塞主线程，您应该使用JavaFX任务或服务概念，详见此处：http://docs.oracle.com/javafx/2/threads/jfxpub-threads.htm
