------------------------------------

             Summary: CAS Reset fails to shrink some allocations
                 Key: UIMA-4226
                 URL: https://issues.apache.org/jira/browse/UIMA-4226
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
            Reporter: Marshall Schor
            Assignee: Marshall Schor
            Priority: Minor


Cas Reset is designed to prepare a CAS for reuse.  The CAS has many aspects which grow dynamically as needed, such as the heap.  If a particular use of a CAS has a large growth in various aspects, after the reset, some automatic shrinking of these things should happen, but not too fast (since it takes time to expand these).  Investigate these and devise space reclamation strategies that balance reclamation vs need-to-expand in a subsequent reuse of a CAS.
