> I often see the following exception while running some tests
> (ProducerFailureHandlingTest.testNoResponse is one such instance):
> {code}
> [2015-01-19 22:30:24,257] ERROR [Controller-0-to-broker-1-send-thread],
> Controller 0 fails to send a request to broker
> id:1,host:localhost,port:56729 (kafka.controller.RequestSendThread:103)
> java.lang.NullPointerException
>     at kafka.controller.RequestSendThread.doWork(ControllerChannelManager.
> scala:150)
>     at kafka.utils.ShutdownableThread.run(ShutdownableThread.scala:60)
> {code}
> Looking at that code in question, I can see that the NPE can be triggered
> when the "receive" is null which can happen if the "isRunning" is false
> (i.e a shutdown has been requested).
