AWTEventを取得して入力イベントを監視

private static int DELAY = 10 * 1000; //10s
private final Timer timer = new Timer(DELAY, new ActionListener() {
  @Override public void actionPerformed(ActionEvent e) {
    setTestConnected(false);
    Toolkit.getDefaultToolkit().removeAWTEventListener(awtEvent);
    timer.stop();
  }
});
private final AWTEventListener awtEvent = new AWTEventListener() {
  @Override public void eventDispatched(AWTEvent e) {
    if (timer != null && timer.isRunning()) {
      // System.out.println("timer.restart()");
      timer.restart();
    }
  }
};
JButton button = new JButton(new AbstractAction("Connect") {
  @Override public void actionPerformed(ActionEvent e) {
    setTestConnected(true);
    Toolkit.getDefaultToolkit().addAWTEventListener(awtEvent,
        AWTEvent.KEY_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK);
    timer.setRepeats(false);
    timer.start();
  }
});
