[jira] Created: (UIMA-1216) UIMA AS Client Code Doesn't Release CAS
While Handling Process Exception
UIMA AS Client Code Doesn't Release CAS While Handling Process Exception
------------------------------------------------------------------------
Key: UIMA-1216
URL: https://issues.apache.org/jira/browse/UIMA-1216
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
UIMA AS client framework code caches a CAS before sending (async) request to UIMA AS service. When the reply is received the CAS is retrieved from the cache, the client (user) code is called via a listener and the CAS is subsequently released. For synchronous calls the user code is responsible for each CAS release. When a reply is received (for both sync and async send), the exception handler notifies the user code but never releases the CAS. This may lead to hangs and may impact performance since some CASes are never released.

Attachment: uimaj-as-jms-UIMA-1216-patch.txt
Modified UIMA-AS client code to release CASes while handling a process exception. The code releases a CAS and removes CAS entry from the cache after calling user code( listener).
