[jira] [Commented] (SAMZA-1257) StandAlone LeaderElector sometimes passes null listener in DataChange subscription.

    [ https://issues.apache.org/jira/browse/SAMZA-1257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993880#comment-15993880 ] 

Navina Ramesh commented on SAMZA-1257:
--------------------------------------

[~boryas] I suspect this will be resolved from the PR in [SAMZA-1150|https://issues.apache.org/jira/browse/SAMZA-1251] . Apart from removing timer dependency, it also simplifies the LeaderElectionListener and PredecessorChangeHandler .

> This causes NPE.
