我刚刚安装了最新版本的 Netbeans ( 7.2 ) 并尝试在其中运行现有的 Swing 项目。我得到以下异常:
堆栈跟踪:

有问题的方法如下所示:
@Override
public boolean add( InitData e ) {
boolean returnValue = super.add( e );
Collections.sort( this, c );
return returnValue;
}
奇怪的是,只有当我将项目属性设置为“保存时编译”时才会出现异常。当该选项未选中时,它运行良好。在以前的 NetBeans 版本中我们没有遇到这样的问题。这只是一个巧合,我应该在其他地方寻找这个错误的来源还是有人遇到过类似的问题?在此先感谢您的帮助。
