The UIMA core code fails to unlock a CAS if there is an exception in
CasMultiplier's next() or hasNext() methods
----------------------------------------------------------------------------------------------------------------
Key: UIMA-1718
URL: https://issues.apache.org/jira/browse/UIMA-1718
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Jerry Cwiklik
Fix For: 2.3
If there is an exception in user's Cas Multiplier hasNext() or next() method,
the framework does not unlock the input CAS. If an application attempts to
reset a CAS that failed in above methods, the following is produced:
CASAdminException: Can't flush CAS, flushing is disabled.
Modify AnalysisComponentCasIterator (an inner class of
PrimitiveAnalysisEngine_impl) to call
((CASImpl)mInputCas).restoreClassLoaderUnlockCas();
in both hasNext() and next() while handling an exception thrown from user's
code.
