> On a user/group lookup failure, JniBasedUnixGroupsMapping and JniBasedUnixGroupsNetgroupMapping are logging the
> full stack trace at WARN level.  Since the caller of these methods is already logging errors, this is not needed.  In branch-1, just one line is logged, so we don't need this change there.
