> Getting ArrayIndexOutOfBoundsException if we pass more arguments than actual
> number arguments. And if we pass lesser number of arguments then getting null
> values. It's not problem for built-in functions because we are using function
> name and number arguments combination key for lookup built-in functions in
> the the map. It's problem for UDF functions.
