title: ScheduledExecutorService start stop several times
body: <p>I am using <a href="http://download.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledExecutorService.html#scheduleAtFixedRate%28java.lang.Runnable,%20long,%20long,%20java.util.concurrent.TimeUnit%29">ScheduledExecutorService</a>, and after I call it's <a href="http://download.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html#shutdown%28%29">shutdown</a> method, I can't schedule a Runnable on it. Calling <code>scheduleAtFixedRate(runnable, INITIAL_DELAY,
                   INTERVAL, TimeUnit.SECONDS)</code> after <code>shutdown()</code> throws java.util.concurrent.RejectedExecutionException. Is there another way to run a new task after <code>shutdown()</code> is called on <a href="http://download.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledExecutorService.html#scheduleAtFixedRate%28java.lang.Runnable,%20long,%20long,%20java.util.concurrent.TimeUnit%29">ScheduledExecutorService</a>?</p>
