Input CAS is returned back to the client while subordinate CASes are still in
play in the aggregate
---------------------------------------------------------------------------------------------------
Key: UIMA-786
URL: https://issues.apache.org/jira/browse/UIMA-786
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Affects Versions: 2.2.1
Reporter: Jerry Cwiklik
When an input CAS is returned from a Cas Multiplier, an Aggregate immediately
returns it back to the client with no check if the subordinate CASes (those
produced from the input CAS) are still in "in-play" in other delegates. Upon
receiving the input CAS reply, the client assumes success and sends a CPC.
Meanwhile, the CASes still in-play may cause Exceptions and termination of the
aggregate. The CPC sent to the service may never be replied to leading to a
hang.
