----------------------------------------------
Resolution: Fixed
> Deserialization of array subtypes fails (form6)
> -----------------------------------------------
>
> Key: UIMA-6318
> URL: https://issues.apache.org/jira/browse/UIMA-6318
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Reporter: Richard Eckart de Castilho
> Assignee: Richard Eckart de Castilho
> Priority: Major
> Fix For: 3.2.0SDK

>
> When serializing, the form 6 binary serializer does use a diff/delta encoding
> for certain values. A value is shortened by storing it as a delta to a
> previously stored value. The previously stored values are maintained in
> relation to the feature structure types.
> When an XMI file is de-serialized in UIMAv3, UIMA creates subtypes of FSArray
> by default.
> It appears that when serializing a CAS containing such subtypes, the subtype
> ID is stored in the CAS and the delta encoding is performed per subtype.
> However, when deserializing, the code tries to resolve the delta values
> against the hard-coded FSArray, causing an exception.
> The issue can be worked around by setting the system property
> {{uima.disable_subtype_fsarray_creation}} to {{true}}.
