------------------------------------------------
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:
{code}
org.apache.uima.analysis_engine.AnalysisEngineProcessException: Annotator
processing failed.
