[jira] [Created] (UIMA-5102) auto set missing AnnotationBase
sofaRef feature
Marshall Schor created UIMA-5102:
------------------------------------
Summary: auto set missing AnnotationBase sofaRef feature
Key: UIMA-5102
URL: https://issues.apache.org/jira/browse/UIMA-5102
Project: UIMA
Issue Type: Improvement
Components: Core Java Framework
Affects Versions: 2.9.0SDK
Reporter: Marshall Schor
Assignee: Marshall Schor
Priority: Minor
Fix For: 3.0.0SDKexp, 2.9.1SDK
This Jira describes a possible approach to automatically recovering from an error condition, which might be implemented.
Sometimes, the sofa feature of a FS which is a subtype of AnnotationBase is missing (is null) when the FS is being added to the indexes of some particular CAS View. One way this can happen is during (lenient) deserialization of XMI or XCAS CASes, after some update has occurred to the type system, which changes a type from not being a subtype of AnnotationBase, to having that as a supertype.
In this case (where the sofa reference is null), instead of throwing an exception, set the sofa reference to the likely proper value - the sofa that corresponds to the view it is being indexed in. If there is no sofa for that view (unlikely but possible), throw an exception.
If this recovery is done, output a diminishing frequency log message about it.
