我剛剛安裝了最新版本的Netbeans（7.2），並嘗試運行其中的現有Swing項目。我有以下異常：「在Netbeans 7.2中啓動項目時，異常代碼屬性不是本機或抽象類中的異常」

問題的方法是這樣的：
@Override
public boolean add(InitData e) {
boolean returnValue = super.add(e);
Collections.sort(this, c);
return returnValue;
}
奇怪的是，當我設置項目屬性的例外只配備「編譯保存」。當選項未選中時，它運行良好。在以前的NetBeans版本中，我們沒有這樣的問題。這只是一個巧合，我應該尋找其他地方的這個錯誤的來源或有任何人有類似的問題？在此先感謝您的幫助。
