Subject [jira] [Created] (S4-74) NullPointerException on TCPEmitter.onChange()
Date Mon, 09 Jul 2012 08:59:35 GMT
Daniel Gómez Ferro created S4-74:

             Summary: NullPointerException on TCPEmitter.onChange() 
                 Key: S4-74
             Project: Apache S4
          Issue Type: Bug
    Affects Versions: 0.5
            Reporter: Daniel Gómez Ferro

TCPEmitter is registering itself as a listener in its constructor: {{this.topology.addListener(this);}}

The topology is triggering a refresh before the TCPEmitter is fully constructed, so TCPEmitter.partitionNodeMap
is still null during onChange() execution.

TCPEmitter shouldn't register itself as a listener until it's fully built, see
(Don't publish the "this" reference during construction)
