> UIMA AS uses one (shared) instance of a cache where intermediate state
> information is kept (and changed) for each CAS during processing. This cache
> is shared among all colocated components. In complex deployments involving
> colocated, multi-level aggregates CAS states changed by one aggregate cause
> problems in other aggregates. Particularly when making decisions when to
> release a CAS. In such deployments hangs may occur.
> Add a private (non-shared) cache to each UIMA AS controller where the state
> of each CAS is kept. CAS instance should be kept in the global InProcessCache
> that is shared by all colocated UIMA AS services.
