Marshall Schor commented on UIMA-6243: -------------------------------------- on v3, failure happens on thatCASCanBeDefinedWIthoutJCasWrappersAndTheyComeInWithAnnotators and thatAnnotatorsCanLocallyUseDifferentJCasWrappers. I will investigate. > 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 > Priority: Major > > 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}}.
