> RoundRobinUserResolver.parseUserList() has a bug in obtaining list of groups for each user --- in the sense that the list is not cleared before obtaining groups list for the next user. So if the first line has some groups, then from 2nd
> line onwards, the validation of "whether the users(in the next lines) are also having group names in those lines" is useless as the list is already nonempty.
> For example, users-list-file content as shown below also is valid as per parseUserList():
> ------------------
> user1,group1
> user2,
> user3,
> user4,
> ------------------
