code: @Override
      public void end(final Xid _xid,
                      final int _flags)
      {
          AbstractResource.LOG.trace("end resource {}, flags {}" + _flags, _xid, _flags);
      }
docs: The method ends the work performed on behalf of a transaction branch.
  Normally nothing must be done, because an instance of a resource is only
  defined for one transaction.
  
  @param _xid      global transaction identifier
  @param _flags    flags
