is this a java memory leak

Question

update: looks like it's not a memory leak, would someone create on based on an extension of this example?
Original question: Suppose I create and starts a thread that does not terminate, the thread creates an object and references as long as it's alive. See the following code. Would the JVM garbage collect x? would this be considered a memory leak?

public class MyRunnable implements Runnable{

    public void run(){
      X x = new X();
      while(true){}
   }
}

Thread t = new Thread(new MyRunnable());
t.start();

Answer 1

The thread never terminates so the garbage collector will never free x. However if you never really use x it it might be optimized out. If you do use x this can not be a memory leak - you use the memory.
