它在最新版本中没有，但是在最新版本中，尽管我只单击了一次，但它可以工作两次。
public void mouseClicked(MouseEvent e) {
((MouseListener)a).mouseClicked(e);
((MouseListener)b).mouseClicked(e);
}
代码来自库类AWTEventMulticaster.class。似乎当我单击一次时，侦听器会两次唤醒。但是奇怪的是，一个事件听众可以工作两次。不仅如此，所有鼠标事件都已更改为工作两次，所以我的所有代码都毁了。有什么解决办法吗？
更多信息在这里。首先，是我的鼠标监听程序的代码。
Label1.addMouseListener(new MouseAdapter()//Begin

String s = "/image/\uBE14\uB85D "+Integer.toString(cn)+"-"+Integer.toString(Label1.getCardNumY())+".png";
ImageIcon im = new ImageIcon(Game.class.getResource(s));
Label1.setImage(im.getImage());
Label1.setIcon(setIconScale(im, Label1.getCardNumX(), Label1.getCardNumY(), 'L'));
Label1.setIsCard(false);
}
else if(Label1.getIsCard()==true)

Label1.setBounds(70, 600, 150, 150);
}

ImageIcon im;
if(Label1.getIsFlipped()==true)

RotatedIcon i = new RotatedIcon(im, (0 - (Label1.getRot()*(90.0))));
Label1.setIcon(i);
Label1.setBounds(70, 600, 150, 150);
}
else if(Used[0]!=1)
{

}
}
Label1.setBounds(70, 600, 150, 150);
Label1.setIsPressed(false);
}
}
public void mouseClicked(MouseEvent e)
{
if(Label1.isCard==false)
{if(e.getButton()==MouseEvent.BUTTON3){
Label1.changeIsFlipped();
}
else if(e.getButton()==MouseEvent.BUTTON1){
