You should NOT pass null as arguments array. Use either new Object[0] or 
  as alternative since Rhino 1.5R5 Context.emptyArgs

Also "if ((fRunStrat instanceof Function && fRunStrat !=null ))" is 
equivalent to "if ( fRunStrat instanceof Function )" since "instanceof" 
gives false for null argument.
