界: Code Quality

コードの質が低いと、予測できない動作につながります。ユーザーの視点には、それがしばしば使い勝手の悪さとなって現れます。攻撃者にとっては、予期せぬ方法でシステムにストレスを与える機会となります。

Code Correctness: Call to Thread.run()

Java/JSP

Abstract

プログラムは start() をコールする代わりに、スレッドの run() メソッドをコールします。

Explanation

ほとんどの場合、Thread オブジェクトの run() メソッドの直接コールはバグです。プログラマは制御の新規スレッドを開始しようとして、誤って start() の代わりに run() をコールしたため、run() メソッドがコーラーの支配下のスレッドで実行されます。

例 1: 次の Java プログラムからの抜粋は、start() の代わりに誤って run() をコールしています。


    Thread thr = new Thread() {
      public void run() {
        ...
      }
    };

  thr.run();
