The driver is working correctly here.

You can only set the resultset type when creating the statement, like so:

> pstmt = conn.prepareStatement("select name, name from amz.product_detail_items order by name", ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);

ResultSet.setFetchDirection() is used to hint to the driver about the
expected order of resultset use, not to set the resultset type. It
expects one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or
ResultSet.FETCH_UNKNOWN. The driver is (correctly) complaining that
you're giving it some other value.

The java.sql javadoc covers all this.
