There is nothing tricky there:
In java every record in the stream passed to closewith() will be fed back.
(And closeWith returns this stream).
In scala its even clearer as the stepfunction returns 2 streams in a tuple.
The first one is the feedback the second is the output.
The methods are not the same but the functionality is equivalent.
