> The above test deploys 5 instances of synchronous aggregate containing a CM
> and a NoOp Annotator. The CM generates 1 CAS for each input CAS. Total of 5
> CASes are sent to the service for processing. Some of the CASes are processed
> and returned back to the client. I am not totally sure what the problem is at
> this time. It seems like the ASB is trying to release a child CAS when the
> above exception occurs. All instances of sync aggregates share Resource
> Manager containing common CasManager. Unable to reproduce this problem on
> Linux, Windows or Mac.
> Further diagnosis points toward an issue with the UIMA Java SDK, for use
> cases where multiple instances of an aggregate (containing a Cas Multiplier)
> are created and run using a shared common UIMA Context / Resource Manager.
> Several parts of the Resource Manager are not thread safe.
> Figure out where things like getEmptyCas need to be synchronized.
> Come up with a better test case (that isn't so intermittent).
