ThreadDeath example. The main thread starts a new thread, then stops the new thread. The new thread catches the ThreadDeath exception, giving it a chance to clean up, before rethrowing the exception and terminating.

Foo.java

package nl.martijndwars.oshell;

public class Foo {
  public static void main(String[] args) throws InterruptedException {
    Thread thread = new Thread(new Bar());
    thread.start();

    Thread.sleep(3000);
    thread.stop();
  }

  static class Bar implements Runnable {
    @Override
    public void run() {
      try {
        repeat();
      } catch (ThreadDeath e) {
        System.err.println("Caught ThreadDeath, but I will loop anyway. Muahahah!");

        repeat();
      }
    }

    private void repeat() {
      while (true) {
        System.out.println("Hi");
        try {
          Thread.sleep(1000);
        } catch (InterruptedException e) {
          e.printStackTrace();
        }
      }
    }
  }
}
