Edward Yoon commented on HADOOP-2297:
-------------------------------------

This is my test code :

{code}

  static class InvokeLauncher extends Thread {
    private String[] newArgs;
    private Method main;

    public InvokeLauncher(Method main, String[] newArgs) {
      this.newArgs = newArgs;
      this.main = main;
    }

    public void run() {
      try {
        try {
          main.invoke(null, new Object[] { newArgs });
        } catch (IllegalAccessException e) {
          e.printStackTrace();
        } catch (InvocationTargetException e) {
          e.printStackTrace();
        }
      } catch (IllegalArgumentException e) {
      }
    }

    public Thread.UncaughtExceptionHandler getUncaughtExceptionHandler() {
      return new Thread.UncaughtExceptionHandler() {
        public void uncaughtException(Thread t, Throwable e) {
        }
      };
    }
  }
{code}
