> 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.
