> When the STC decides that a method reference is being provided for a type that is not a functional interface, it prints the error 
> {code}
> The argument is a method reference, but the parameter type is not a functional interface
> {code}
> without specifying what it believes the parameter type _is_. It would be helpful for troubleshooting to identify the parameter type.
