程序'java.ori'收到X Window System錯誤

Question

我在Ubuntu 11.10上有一個桌面應用程序，我已經實現了一個功能，當任何用戶點擊一個特定按鈕時，會打開一個輸入對話框並要求用戶輸入。

public void actionPerformed(ActionEvent e) {
       //Shows a input dialog asking the template ID to verify
       String id = JOptionPane.showInputDialog(rootPane, 
            "Enter the Enrolled ID to verify.", "Verify", 
            JOptionPane.QUESTION_MESSAGE);
}

因此用戶填寫值並單擊“確定”按鈕甚至嘗試關閉對話框應用程序獲取錯誤並崩潰。

錯誤：

The program 'java.ori' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 2262 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

誰能幫我解決這個問題？ 提前致謝。

我相信，rootPane不適合作為JDialog的父級，它將由JOptionPane顯示。 它應該是JFrame或其他JDialog。
