Potential ClassCastException in CasPool
---------------------------------------
Key: UIMA-1499
URL: https://issues.apache.org/jira/browse/UIMA-1499
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.3
Reporter: Jörn Kottmann
Fix For: 2.3
The CasPool has a constructor
CasPool(int aNumInstances, Collection aComponentDescriptionsOrMetaData,
Properties aPerformanceTuningSettings, ResourceManager
aResourceManager)
where aComponentDescriptionsOrMetaData is a collection which can contain
according
to javadoc "AnalysisEngineDescription, CollectionReaderDescription,
CasConsumerDescription or ProcessingResourceMetaData objects"
A reference of the Collection is passed to fillPool which passes the
Collection
to a CasDefinition constructor which then casts everything to
ProcessingResourceMetaData,
which will result in a ClassCastException in the case of
AnalysisEngineDescription,
CollectionReaderDescription and CasConsumerDescription objects.
