> Project: Apache Curator
> Issue Type: Bug

>
> Whenever I add zookeeper servers by using reconfig API of the curator client,
> it always throw ArrayIndexOutOfBoundsException.
> If there are no servers to add or remove when using reconfigure API of
> ZooKeeperAdmin, I think it must pass not empty list parameter but null to
> reconfigure API. Because ZooKeeperAdmin tries to join strings by accessing
> first index of the server list.
> Please refer to the link below.
