Marshall Schor commented on UIMA-3141:
--------------------------------------
Richard makes an interesting point. I think it's also generalizable, something
along these lines:
If a target type system is missing type X but has a super-type of X, to pick
the most specific supertype (say Y), and have the FS of type X get serialized
as an instance of type Y, which is what I think was suggested above, as special
handling for document annotation. Is this a good direction to go?
> Binary CAS format 6 + type filtering fails to deserialize document annotation
> correctly

> 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.
