Hi,

The following code generates an exception shown below. Commenting out the refreshRow() call would solve the issue. This exception happens only in driver versions 42.2.13 and above. Is this a bug in the driver?

        ResultSet rs = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE ).executeQuery(sql);
        rs.next();
        rs.updateDate("start_date", Date.valueOf("2020-01-01"));
        rs.updateDate("end_date", Date.valueOf("2020-12-31"));
        rs.updateRow();
        rs.refreshRow();
        rs.updateDate("end_date", Date.valueOf("2020-12-30"));
        rs.updateRow(); // Exception occurs at this line.


Exception in thread "main" java.lang.IllegalArgumentException: Attempted to write to readonly tuple

Thanks,
