------------------------------------
Summary: edge cases need Flattened index invalidation
Key: UIMA-4542
URL: https://issues.apache.org/jira/browse/UIMA-4542
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.8.0SDK
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 2.8.1SDK
There are some edge cases that invalidate the flattened indexes, that are not
accounted for. One is what happens when a pipeline transitions from non-JCas
to JCas generators. Any flattened index built before this transition will have
the incompatible kinds of Java Cover classes.
The other happens within a PEAR context - during that part of a pipeline, the
classpath is altered, and the PEAR could be redefining the Java cover classes.
There may be others. For now, because measurements in real-life situations
didn't show much if any improvement, the fix is to disable this feature.
