      Description

      If the kafka mirroring embedded consumer receives a new topic watcher notification, it runs into the following exception

      [2011-11-23 02:49:15,612] FATAL java.lang.IllegalThreadStateException (kafka.consumer.ZookeeperTopicEventWatcher)

      This happens since it tries to start a thread which has finished executing
