Jaroslaw Cwiklik commented on UIMA-6210:
----------------------------------------
It looks like the exception is logged but no action is taken when
collectionProcessingComplete() throws an exception. I can certainly invoke
registered callbacks but one worry I have is that it may break existing apps
which will now see a failure. Just looking for consensus that calling listeners
with an error (previously silent) on cpc failure is the right thing to do.

> CPE swallows exceptions thrown in collectionProcessComplete

> Key: UIMA-6210
> URL: https://issues.apache.org/jira/browse/UIMA-6210
> Project: UIMA
> Issue Type: Improvement
> Components: Collection Processing
> Reporter: Richard Eckart de Castilho
> Assignee: Jaroslaw Cwiklik
> Priority: Major
>
> When an analysis engine is deployed into a CPE and run, then exceptions
> thrown by the {{collectionProcessComplete}} method of the analysis engine are
> swallowed by the CPE {{ProcessingContainer_Impl}}.
> Instead of being swallowed, I would expect them to be reported to any
> {{StatusCallbackListener}} registered with the CPE.
