계: Code Quality

코드 품질이 낮으면 예측할 수 없는 동작이 발생합니다. 사용자 입장에서는 사용 편의성이 떨어지는 것으로 나타나는 경우가 많습니다. 공격자에게는 예상치 못한 방법으로 시스템에 부담을 줄 수 있는 기회가 됩니다.

Code Correctness: Call to Thread.run()

Java/JSP

Abstract

이 프로그램은 start()를 호출하는 대신 스레드의 run() 메서드를 호출합니다.

Explanation

대부분의 경우 Thread 개체의 run() 메서드를 직접 호출하는 것은 버그입니다. 프로그래머는 새 제어 스레드를 시작하려 했지만 실수로 start() 대신 run()을 호출했기 때문에 run() 메서드는 호출자의 제어 스레드에서 실행됩니다.

예제 1: 다음의 발췌된 Java 프로그램은 실수로 start() 대신 run()을 호출합니다.


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

  thr.run();
