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:
java.lang.NullPointerException: null
