[jira] [Closed] (UIMA-2324) Fix NPE in UIMA AS aggregate which
occurs while recovering from Cas Multiplier failure
[ https://issues.apache.org/jira/browse/UIMA-2324?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jerry Cwiklik closed UIMA-2324.
-------------------------------
Resolution: Fixed
The aggregate was not associating a delegate key with a CAS to be processed by the delegate. While recovering from a delegate failure, the aggregate was trying to determine the endpoint of the delegate using a key that was not set.
