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

             Summary: NullPointerException in CasSerializerSupport when called from JsonCasSerializer and features reference the cas:NULL element
                 Key: UIMA-4915
                 URL: https://issues.apache.org/jira/browse/UIMA-4915
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
    Affects Versions: 2.8.1SDK, 2.7.0SDK
         Environment: All
            Reporter: Philip Parker


When serializing a CAS, if there are references to the NULL element (<cas:NULL xmi:id="0"/>) in the features for an annotation, a NullPointerException is thrown at line 693 of CasSerializerSupport. It appears that the ll_getTypeForCode(0) returns null, resulting in a NullPointerException when the "getName()" method is called on the return object.

The same CAS can successfully be serialized to XML using the XmlCasSerializer.
