Richard Eckart de Castilho commented on UIMA-3141:
--------------------------------------------------
If the custom sub-type of DocumentAnnotation is part of the target type system,
it works (not verified in exactly the given test case, but in the context form
which this test was distilled).
Since the document annotation is a special annotation in UIMA, it may require
special handling. I would expect that all features are set if they are
available on the document annotation, even if the type of the document
annotation is not the same.
> Binary CAS format 6 + type filtering fails to deserialize document annotation

> Key: UIMA-3141
> URL: https://issues.apache.org/jira/browse/UIMA-3141
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Affects Versions: 2.4.1SDK
> Reporter: Richard Eckart de Castilho
> Assignee: Marshall Schor
>
> When a custom document annotation type is used, the language is not properly
> restored after deserializing from CAS format 6.
> Expected: deserialized CAS has language "latin"
> Actual: deserialized CAS has language "x-unspecified"
> If the line {{sourceCas.addFsToIndexes(ma);}} is commented out, the code
> works.
