 * An exception indicating a problem in the inference engine.
 * The typical scenario is that the inference engine tries to resolve clause sets 
 * from an external source (e.g., an SQL database or a web service), this fails and the 
 * exception handling policy in the inference engine is set to exception bubbling (forwarding).
