Subject [jira] Created: (SYNAPSE-288) AbstractPollingTransportListener fails to cancel timer on destroy

AbstractPollingTransportListener fails to cancel timer on destroy
-----------------------------------------------------------------

                 Key: SYNAPSE-288
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-288
             Project: Synapse
          Issue Type: Bug
          Components: Transports
    Affects Versions: NIGHTLY
            Reporter: Andreas Veithen
            Priority: Minor


After AbstractPollingTransportListener#destroy is called, the following exception is triggered:

Exception in thread "PollTimer" java.util.concurrent.RejectedExecutionException
	at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:1477)
	at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:384)
	at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:856)
	at org.apache.synapse.transport.base.threads.NativeWorkerPool.execute(NativeWorkerPool.java:55)
	at org.apache.synapse.transport.base.AbstractPollingTransportListener$1.run(AbstractPollingTransportListener.java:81)
	at java.util.TimerThread.mainLoop(Timer.java:512)
	at java.util.TimerThread.run(Timer.java:462)

Obviously the timer still tries to schedule a new task after the worker pool has been shut
down. I suspect that the reason is that AbstractTransportListener#stop doesn't call stopListeningForService,
given that AbstractPollingTransportListener cancels the timers there.
