界: Time and State
分散式運算與時間和狀態相關。也就是說，為了使多個元件進行通訊，必須共用狀態，並且這一切都需要時間。
大多數的程式設計師將他們的工作擬人化。他們想採用一種控制執行緒來執行整個程式，就像他們必須自己完成這項工作一樣。但是，現代的電腦可以非常快速地切換工作，並且在多核心多 CPU 或分散式系統中，兩個事件可能恰好同時發生。瑕疵急於填補程式設計師在程式執行模型與實際情況之間的差距。這些瑕疵與執行緒、處理序、時間和資訊之間的意外互動有關。這些互動透過共用狀態發生：信號、變數、檔案系統，以及基本上任何可以儲存資訊的項目。
J2EE Bad Practices: JVM Termination
Abstract
Web 應用程式不應嘗試關閉自身的容器。
Explanation
讓 Web 應用程式嘗試關閉自身的容器是不對的。呼叫終結方法可能是殘餘除錯程式碼的一部分，或是從非 J2EE 應用程式所匯入程式碼的一部分。
