I am using a ThreadPool via ExecutorService. By calling shutDownNow() it interrupts all running threads in the pool. When this happens I want these threads to give up their resources (socket and db connections) and simply die, but without continuing to run anymore logic, eg: inserting anything into the DB. What is the simplest way to achieve this? Bellow is some sample code:

public void threadTest() {
    Thread t = new Thread(new Runnable() {

            public void run() {
                try {
                    Thread.sleep(999999);
                } catch (InterruptedException e) {
                    //invoke thread suicide logic here
                }
            }
        });
    t.start();

    t.interrupt();
    try {
        Thread.sleep(4000);
    } catch (InterruptedException e) {
    }
}
