-------------------------------
    Priority: Blocker  (was: Major)

>             Project: UIMA
>          Issue Type: Bug
>          Components: uimaFIT
>    Affects Versions: 2.1.0uimaFIT

>            Priority: Blocker

> 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.
