[ https://issues.apache.org/jira/browse/RIVER-402?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Greg Trasuk updated RIVER-402:
------------------------------
Fix Version/s: (was: River_2.2.1)
I believe this fix is in trunk but not 2.2.1 maintenance release.
> NullPointerException in LookupCacheImpl.notifyServiceMap
> --------------------------------------------------------
>
> Key: RIVER-402
> URL: https://issues.apache.org/jira/browse/RIVER-402
> Project: River
> Issue Type: Bug
> Components: net_jini_lookup
> Affects Versions: River_2.1.2
> Reporter: Neil Ferguson
> Assignee: Peter Firmstone
>
> One of our automated tests fails periodically (roughly 1 in 5 times), due to the ServiceDiscoveryListener.serviceRemoved method not getting called sometimes. This seems to be due to a NullPointerException in LookupCacheImpl.notifyServiceMap, which seems to be triggered by us calling JoinManager.terminate. This is on Apache River 2.2.0.
