java - ExecutorService is not shutting down -


i have following code

    executorservice es = executors.newsinglethreadexecutor();     es.submit(new runnable() {            @override public void run()             {                   while(true);              }    });  es.shutdownnow();

the problem executorservice doesn't shutdown after call shutdownnow. documentation says attempts stop actively executing tasks.

so why es failing shutdown?

i did , worked: 

    executorservice es = executors.newsinglethreadexecutor();     es.submit(new runnable() {            @override public void run()             {                   while(!thread.currentthread().isinterrupted());              }    });     es.shutdownnow();

the reason shutdownnow doesn't terminate thread. interrupts running threads.
