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。

这似乎是 中的一个错误NetBeans .

当这个异常发生时，让我们在代码中出错(例如

@Override
**efefefefef**
public boolean add( InitData e ) {
    boolean returnValue = super.add( e );
     Collections.sort( this, c );
    return returnValue;
}

)

保存它，当 Netbeans 显示错误时，将其更正回来。我试图清除项目，从缓存中删除所有内容，但什么也没发生。但这种方式对我有帮助。
