org.springframework.boot.autoconfigure.orm.jpa.DatabaseLookup is not used anywhere and is not public so it should either be deleted or made public. I personally would like to see the latter.

Good catch @biergit. Its use was deprecated as of #16172 but we forgot to flag the class itself. As for making it public, there's really no reason for us to do so as it's a utility class we wouldn't use ourselves.
