> UIMA AS Client Code Doesn't Release CAS While Handling Process Exception

> 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 containing an exception 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.
