----------------------------------
Summary: AnalysisEngineFactory doesn't pass
AnalysisEngine.PARAM_NUM_SIMULTANEOUS_REQUESTS parameter correctly to
UIMAFactory when creating a new engine
Key: UIMA-4199
URL: https://issues.apache.org/jira/browse/UIMA-4199
Project: UIMA
Issue Type: Bug
Components: uimaFIT
Affects Versions: 2.1.0uimaFIT
Reporter: Faisal Feroz
When {{org.apache.uima.fit.factory.AnalysisEngineFactory.createEngine(Class<?
extends AnalysisComponent>, Object...)}} is called for creating a
multi-threaded engine instance by passing in
AnalysisEngine.PARAM_NUM_SIMULTANEOUS_REQUESTS and some integer value in
configurationData. It creates AnalysisEngineDescription object from the data
and calls
{{org.apache.uima.fit.factory.AnalysisEngineFactory.createEngine(AnalysisEngineDescription,
Object...)}} method which passes in null in {{aAdditionalParameters}} when
calling {{UIMAFramework.produceAnalysisEngine}}. The respective method looks
for {{AnalysisEngine.PARAM_NUM_SIMULTANEOUS_REQUESTS}} as per the following
code:
{code:java}
boolean multiprocessing = (aAdditionalParams != null)
&&
aAdditionalParams.containsKey(AnalysisEngine.PARAM_NUM_SIMULTANEOUS_REQUESTS);
{code}
which is never found and the required {{MultiprocessingAnalysisEngine_impl}} is
never created.
