because this line add synchronized
https://github.com/apache/bookkeeper/blob/c4fa8c20131fb5e52b7448ee6ee1491bf9e870fa/bookkeeper-server/src/main/java/org/apache/bookkeeper/zookeeper/ZooKeeperClient.java#L260
this line is sync method, so I remove the synchronized.
this interface is not a consistent method, I think add volatile is enough
