ExecuterService hanged

I am facing some issue where executer service gets hanged up.

I wanted to test some scenario where one of runnable thread gets stuck as it involves with lot of systems and ultimately leads to executer hangup.

For that I created one testing scenerio where i created 5 threads through executer service and write an infinite loop in one of the thread.I see the code is getting stuck in that loop and not comming to shutdown/shoutDownNow method of main thread. What will be the priority of the main thread execution. How can we enforce shutdown in this case?

We can not enforce shut down until any of the runnable task is still in progress (non-daemon thread). You can try loop with large iterations and see. eg.

ExecutorService e = Executors.newCachedThreadPool();
e.execute(new Runnable() {

@Override
public void run() {
    for(int i =0 ; i< 5000; i++){
    System.out.println("run me in a different thread" + i);
    }

}
});
e.shutdown();
