    GetBoundsBug frame = new GetBoundsBug();
    Button button = new Button("Click here!");
    button.addActionListener(frame);
    frame.add(button);
    frame.setSize(300, 300);
    frame.setVisible(true);
  }

  @Override
  public void actionPerformed(ActionEvent event) {
    Rectangle bounds = getBounds();
    bounds.y--;
    setBounds(bounds);
    bounds.y++;
    setBounds(bounds); …
