Subject [jira] [Created] (UIMA-6243) JCas returns Annotation when asked for a specific subtype
Date Wed, 10 Jun 2020 18:56:00 GMT
Richard Eckart de Castilho created UIMA-6243:
------------------------------------------------

             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:

org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator processing failed.
