界: Code Quality

代码质量不佳会导致不可预测的行为。对于用户来说，通常表现为可用性差。对于攻击者来说，提供了以意外方式对系统施加压力的机会。

Code Correctness: Call to Thread.stop()

Abstract
程序调用了线程的 stop() 方法，这可能会导致资源泄露。
Explanation
在多数情况下，直接调用 Thread 对象的 stop() 方法会是一个 bug。程序员希望阻止线程运行，但是没有意识到这种阻止线程的方式并不合适。Thread 中的 stop() 函数会导致 Thread 对象中的任意位置出现 ThreadDeath 异常，这可能会导致对象出现不一致状态，并且会泄露资源。由于此 API 本质上并不安全，因此很久以前就已弃用。

示例 1：以下内容摘录自 Java 程序，其错误地调用了 Thread.stop()。


  ...
  public static void main(String[] args){
    ...
    Thread thr = new Thread() {
      public void run() {
        ...
      }
    };
    ...
    thr.start();
    ...
    thr.stop();
    ...
  }
