>
> NPE is thrown in AsynchAECasManager.iniitalize method if log level > INFO and 
> UIMA AS client application does not provide initial heap size in 
> ApplicationContext. If the context is not provided, the UIMA AS client 
> initialize() method passes null for performanceTuningSettings when calling 
> AsynchAECasManager.initialize(). Inside that method, the  
> performanceTuningSettings is dereferenced causing NPE.
