> If I create a consumer connector, and create some KafkaStreams using a TopicFilter, but then never send any messages, and then call shutdown on the connector, the KafkaStreams never get notified of the shutdown.
> Looking at ZookeeperConsumerConnector, in the method 'sendShutdownToAllQueues', It appears the current implementation is dependent on receiving at least 1 message with a topic, before initializing the list of topicThreadIdAndQueues, to send the shutdownCommand to.
