無法提示javaFX中的信息消息或警告消息/

我從here得到了javaFX中解決rubik的魔方的源代碼。有用於提示對話框，用戶輸入或進行確認作爲代碼：無法提示javaFX中的信息消息或警告消息/

Button bSeq = new Button("Sequence"); 
    bSeq.setOnAction(e -> { 
     String response; 
     if (moves.getNumMoves() > 0) { 
      response = 
        Dialogs.create() 
        .owner(stage) 
        .title("Warning Dialog") 
        .masthead("Loading a Sequence").lightweight() 
        .message("Add a valid sequence of movements:\n(previous movements will be discarded)") 
        .showTextInput(moves.getSequence()); 
     } else { 
      response = Dialogs.create() 
        .owner(stage) 
        .title("Information Dialog") 
        .masthead("Loading a Sequence").lightweight() 
        .message("Add a valid sequence of movements") 
        .showTextInput(); 
     } 
     System.out.println("r: " + response); 
     if (response != null && !response.isEmpty()) { 
      rubik.doReset(); 
      rubik.doSequence(response.trim()); 
     } 
    });

和確認對話框：

Button bSc = new Button("Scramble"); 
    bSc.setOnAction(e -> { 
     if (moves.getNumMoves() > 0) { 
      Action response = Dialogs.create() 
        .owner(stage) 
        .title("Warning Dialog") 
        .masthead("Scramble Cube") 
        .message("You will lose all your previous movements. Do you want to continue?") 
        .showConfirm(); 
      if (response == Dialog.Actions.YES) { 
       rubik.doReset(); 
       doScramble(); 
      } 
     } else { 
      doScramble(); 
     } 
    });

但在點擊該bSeq和BSC按鈕沒有對話越來越迅速和例外，我我得到的是：

如果我刪除Diaog.create()和手動輸入的反應，一切工作正常。
