Swing應用程序掛起，多CPU消耗

我想問一下你的幫助來分析線程轉儲。我有一個豐富的SWING應用程序，其中一個用戶聲稱它掛在退出並在後臺運行，消耗很多CPU。我所有的是線程轉儲。「AWT-EventQueue-1」線程對我來說似乎很陌生。Swing應用程序掛起，多CPU消耗
你有什麼想法，什麼地方出了錯？
預先感謝您。

真的很難說，沒有上下文，也沒有看到任何代碼。有人說JWS控制器似乎試圖顯示控制檯。你有沒有嘗試在幾個時刻捕獲線程轉儲？線程轉儲是否隨時間而改變？現在，如果使用'System.exit（0）'，系統應該退出，不管發生什麼。 – 2013-02-19 14:54:37
一個google search的線程轉儲分析，以幫助你明白你在你的手中。
除此之外，您可能還想使用VisualVM進行進一步分析，以檢查GC頻率和堆的使用情況。
如果沒有更多關於您的應用在所謂減速期間所做的事情的信息，那恐怕就是我們唯一可以提供的技巧。
