Jerry Cwiklik updated UIMA-1343:
--------------------------------
Fix Version/s: 2.3AS
> Uima AS aggregate controller should synchronize code that processes CPC
> replies from delegates
> ----------------------------------------------------------------------------------------------
>
> Key: UIMA-1343
> URL: https://issues.apache.org/jira/browse/UIMA-1343
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Fix For: 2.3AS
>
>
> Uima AS aggregate allows concurrent processing of CPC replies from its
> delegates. This creates a problem when two different threads call
> collectionProcessComplete() on the Flow Controller at the same time. The
> result is an ArithmeticException: /by zero. The collectionProcessComplete()
> call should only be done once. Add synchronization to prevent calling
> collectionProcessComplete() more than once.
