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

             Summary: Throw exception if setting FS reference to FS not in CAS
                 Key: UIMA-3429
                 URL: https://issues.apache.org/jira/browse/UIMA-3429
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
    Affects Versions: 2.3
            Reporter: Mike Barborak
            Priority: Minor


It would be helpful if adding a feature structure reference to a CAS for a feature structure that does not exist in that CAS failed quickly and with a clear exception as to the cause. 

In my case I had two CASes and referred to a feature structure in one from a feature structure in another. The exception was a cryptic NPE in BinaryCasSerDes4 during CAS serialization.
