Statement is extended by PreparedStatement, and both classes currently have a field ResultSet resultSet. This led to the unexpected behaviour in #235 where getResultSet() would return null despite the statement having a valid resultSet.
Description
Changed resultSet in Statement from private to protected and removed the extra field from PreparedStatement so that it can inherit the field instead.
