             Summary: ZooKeeper modified events published for unchanged 
endpoints
                 Key: ARIES-2224
                 URL: https://issues.apache.org/jira/browse/ARIES-2224
             Project: Aries
          Issue Type: Bug
          Components: Remote Service Admin
    Affects Versions: rsa-1.16.1
            Reporter: Amichai Rothman


ZookeeperEndpointListener triggers the onChanged handler whenever it receives 
events on any of the recursively watched nodes that contains endpoint data. 
That in turn triggers listener events, either added or modified, depending on 
whether we already have a previous version of the endpoint.

However, sometimes the previously existing endpoint data is identical to the 
new endpoint data, in which case the modified event is triggered even though 
nothing was modified. It should only trigger such an event if there is a real 
change in the endpoint data.
