Stopping a simple Thread

Question

I read the article http://download.oracle.com/javase/6/docs/technotes/guides/concurrency/threadPrimitiveDeprecation.html but it did not helped me much.
Here is a simple scenario that I'm unable to solve.
Consider a misbehaving thread:
public class Nano extends Thread {
     @Override
     public void run() {
          while(true) {
               System.out.println(System.nanoTime());
Assume that the class above is a third party tool and I cannot modify it. (Eg. I cannot add a flag to the loop like - while(keepRunning))
I create a class to run this misbehaving thread, and try to KILL it after a certain timeout:
public class MyThreadDemo {
     public static void main(String[] args) {
          Thread t = new Nano();
          System.out.println("Starting the new thread");
          t.start();
          // Some operation
          t.interrupt();
          System.out.println("Thread is now Stopped. Terminating Application.");
Well, the message "Terminating Application" is printed, but the thread Nano keeps running for ever.
Can you suggest a possible solution, a safe way to stop the thread?

You want two threads in the new JVM.
One control thread that interacts with your original app in the original JVM.
One daemon thread that runs the misbehaving code.
When your original app in your original JVM tells the control thread in the new JVM to exit
there will only be a daemon thread left and the JVM will exit.
