Review Comment:
   Yes, I have the same confusion at first. But look again, it'll find there is 
a (not)! in front of the whole condition. That is:
   ```
   *!* (e.getCause != null &&
           e.getCause.isInstanceOf[TopicExistsException] &&
           !waitForAllPartitionsMetadata(brokers, topic, 
effectiveNumPartitions).isEmpty &&
           topicHasSameNumPartitionsAndReplicationFactor(admin, topic,
             effectiveNumPartitions, replicationFactor)
   )
   ```
