-----------------------------------
Summary: CasPool incorrectly stores references to the InitialView
of each CAS
Key: UIMA-3655
URL: https://issues.apache.org/jira/browse/UIMA-3655
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Eddie Epstein
Assignee: Marshall Schor
For cas pools, getCas returns a handle to the InitialView of an empty CAS,
and stores this handle to match in releaseCas. This breaks for services that
employ sofamapping. The empty CAS is filled from a serialized CAS sent to the
service. It is possible that a CAS received may not contain the view,
CAS.NAME_DEFAULT_SOFA, specified by sofamapping.
Then, when the service tries to return the CAS to the pool, releaseCas blows up
at the first line,
CAS cas = aCas.getView(CAS.NAME_DEFAULT_SOFA);
so the CAS is not returned to the pool ==> CAS leak.
The cas pool should be storing references to the base CAS, which is independent
of views.
