从JFrame创建JFrame时出错

我有一个运行良好的应用程序,它的JFrame是在GameInitializer类的构造函数中启动的,该类接受一些配置参数。我尝试创建一个GUI,允许用户指定这些配置参数,然后单击submit。当用户单击submit时,会创建一个新的GameInitializer对象。我得到的错误是:

Exception in thread "AWT-EventQueue-0" java.lang.Error: Cannot call invokeAndWait from the event dispatcher thread
    at java.awt.EventQueue.invokeAndWait(Unknown Source)
    at javax.swing.SwingUtilities.invokeAndWait(Unknown Source)
    at game.player.humanplayer.view.HumanView.update(HumanView.java:43)

一旦调用submit,就会执行以下代码:

values assigned to parames...   
    new GameInitializer(userName, player, Constants.BLIND_STRUCTURE_FILES.get(blindStructure), handState);

public GameInitializer(String playerName, AbstractPlayer opponent, String blindStructureConfig, AbstractHandState handState){
        beginGame(playerName, opponent, blindStructureConfig, handState);
    }

    public static void beginGame(String playerName, AbstractPlayer opponent, String blindStructureConfig, AbstractHandState handState){
        AbstractDealer dealer;
        BlindStructure.initialize(blindStructureConfig);
        AbstractPlayer humanPlayer = new HumanPlayer(playerName, handState);

        AbstractPlayer[] players = new AbstractPlayer[2];
        players[0] = humanPlayer;
        players[1] = opponent;

        handState.setTableLayout(players);

        for(AbstractPlayer player : players){
            player.initialize();
        }

        dealer = new Dealer(players, handState);

        dealer.beginGame();
    }

它基本上是级联的,并最终在HumanView类中调用这段代码:

public void update(final Event event, final ReadableHandState handState, final AbstractPlayer player) {
        try {
            SwingUtilities.invokeAndWait(new Runnable() {

                public void run() {
                    gamePanel.update(event, handState, player);
                    validate();
                }
            });
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }

        if(event.equals(Event.HAND_ENDING)){
            try {
                if(handState.wonByShowdown() || handState.isSplitPot()){
                    Thread.sleep(3500);
                }
                else{
                    Thread.sleep(1000);
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
