Patrick Hunt updated ZOOKEEPER-66:
----------------------------------
Resolution: Won't Fix
Status: Resolved (was: Patch Available)
Closing this issue.
We don't want to encourage users to use null watchers. There are very limited
cases where a null watcher might be useful - probably just during the initial
"kicking the tires" phase of learning ZK.
Implementing a production client requires the developer to implement a full
watcher that is able to handle events and status changes (resetting watches if
disconnected from the server for example).
