-------------------------------
Resolution: Fixed
Modified code to ignore out of band CASes
> UIMA-AS Not Handling Late Replies Correctly
> -------------------------------------------
>
> Key: UIMA-2477
> URL: https://issues.apache.org/jira/browse/UIMA-2477
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.4.0AS
>
>
> When UIMA-AS aggregate receives late (previously timed out) reply from a
> remote delegate it tries to drop related Flow object from a FC and
> subsequently removes a CAS from its cache. This is wrong. Its up to the FC to
> decide what to do with a timed out CAS. In a scenario when the FC continues
> with a timed out CAS, current code may cause NPEs in the AE and an unexpected
> shutdown of the service if action=terminate on Process error. The code should
> be changed to ignore out-of-band CASes.
