I see little value in this over the much more simple:

      @Override
      public void close() throws SQLException {
          Statement stmt = resultSet.getStatement();
          resultSet.close();
          stmt.close();
      }

:-)

The original SQLException should contain sufficient information. I
don't see "Could not close Statement after closing ResultSet." adding
value.
