As described in the ticket, I've merged MultipartFileArgumentResolver into the RequestPartArgumentResolver. I also think this is a better option since the javadoc for@RequestPart explicitly mentions work with the MultipartFile.
However, I'm unsure if MultipartFileArgumentResolver must be removed now. Probably it can, since the release 6.1 isn't out yet, so it's present only in the pre-releases.
