      Description

      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.
