------------------------------------------------
Summary: 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
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}}.
