Code Correctness: Call to Thread.run()

The program calls a thread's run() method instead of calling start().

In most cases a direct call to a Thread object's run() method is a bug. The programmer intended to begin a new thread of control, but accidentally called run() instead of start(), so the run() method will execute in the caller's thread of control.

Example 1: The following excerpt from a Java program mistakenly calls run() instead of start().

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

  thr.run();
