Subject [jira] [Updated] (UIMA-6243) JCas returns Annotation when asked for a specific subtype
Date Wed, 10 Jun 2020 19:10:00 GMT

     [ https://issues.apache.org/jira/browse/UIMA-6243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Richard Eckart de Castilho updated UIMA-6243:
---------------------------------------------
    Description: 
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.

Looks like this is a UIMAv2 issue only. When running the test against the UIMAv3 master (commit
0211057ad), I do not get any ClassCastException.
