             Summary: JCas returns Annotation when asked for a specific subtype
                 Key: UIMA-6243
                 URL: https://issues.apache.org/jira/browse/UIMA-6243
             Project: UIMA
          Issue Type: Bug
          Components: UIMA
    Affects Versions: 2.10.4SDK
            Reporter: Richard Eckart de Castilho


In a specific classloader topology, a fully initialized JCas with theoretic access to the JCas wrappers of a given type will not return that type but instead returns an instance of {{Annotation}}. This leads to an exception like this:
