------------------------------------------------
Summary: Problem with JCas classes with re-used across different
type systems
Key: UIMA-6468
URL: https://issues.apache.org/jira/browse/UIMA-6468
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Richard Eckart de Castilho
Assignee: Richard Eckart de Castilho
Fix For: 3.4.0SDK
When a JCas wrapper class is loaded, its features are bound to "index"
positions in the type system available at the time that they are loaded.
Normally this works great, even if different type systems are used because the
features defined by the JCas classes have priority and thereby receive stable
index positions.
However, there can be problems in situations where multiple classloaders are
involved such that a JCas class that has been bound to one indexes in type
system would later be bound to other indexes in slightly different type system,
e.g. because the available features change (in a reasonably "compatible" way).
It would be nice if UIMA had a solution for this type of problem.
