next() combines ack() and pull(), requires the subject for a subscription processing to process a message is provided (can be the same) however, because the ability to specify how long to keep the request open can be specified, this functionality doesn't work well with iterators, as an error (408s) are expected and needed to re-trigger a pull in case there was a timeout. In an iterator, the error will close the iterator, requiring a subscription to be reset.
