[jira] Created: (UIMA-965) PrimitiveController doesnt handle exception from the InProcessCache when the service is terminating in a middle of the run

PrimitiveController doesnt handle exception from the InProcessCache when the service is terminating in a middle of the run
--------------------------------------------------------------------------------------------------------------------------

                 Key: UIMA-965
                 URL: https://issues.apache.org/jira/browse/UIMA-965
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
            Reporter: Jerry Cwiklik


Need to handle an exception in the PrimitiveController process() method when the service is being stopped while its producing CASes. InProcessCache may throw an exception in getCacheEntryForCAS(aCasReferenceId) when a given CAS doesnt exist. This could happen during a hard stop. The top level controller may remove entries from the cache which is shared by all collocated services.

[jira] Updated: (UIMA-965) PrimitiveController doesnt handle exception from the InProcessCache when the service is terminating in a middle of the run

Jerry Cwiklik updated UIMA-965:
-------------------------------

    Attachment: uimaj-as-core-UIMA-965-patch.txt

Modified the PrimitiveController code in the process() method to handle exceptions from InProcessCache when try to fetch a non-existent entry. The entry may not exist since a top level controller may have already cleaned up the cache during a forced shutdown.
