All getEngineBy* methods of javax.script.ScriptEngineManager throw NullPointerException if null parameter is given. In fact, spec says that all methods getEngineBy* return null if no such factory was found and NullPointerException is not mentioned at all. It would good to clarify methods behavior in case of null parameter passed.
