[jira] [Created] (RIVER-402) NullPointerException in
LookupCacheImpl.notifyServiceMap
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
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.
Exception as follows:

Neil Ferguson commented on RIVER-402:
-------------------------------------
This seems to happen because the item field passed-in to the notifyServiceMap method is null (I think this is expected, because a service is being removed), and this causes a NPE when trying to create a log message.
Setting the log level to INFO fixes the problem.
