Bug? report : PreparedStatement.setObject(java.util.Date) don't work

Hello.

I've faced problem similar to http://archives.postgresql.org/pgsql-jdbc/2007-06/msg00070.php

Source:
-------------------------------------------------------------------------

package test;

import java.sql.*;
import java.util.*;

public class TestDate{
    public static void main(String[] ags){
        try{
            Class.forName("org.postgresql.Driver");

            Connection con = DriverManager.getConnection(
                "jdbc:postgresql:dbname",
                "user",
                "pass");

            PreparedStatement stmt = 
con.prepareStatement("select * from table_name where column_name = ?");
            stmt.setObject(1, new java.util.Date());
            ResultSet rs = stmt.executeQuery();

            while(rs.next
()){
                System.out.println( rs.getDate(1) );
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

Message:
-------------------------------------------------------------------------
org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of java.util.Date. Use setObject() with an explicit Types value to specify the type to use.

It seemed org.postgresql.jdbc2.AbstractJdbc2Statement#setObject(int, Object) can't
map java.util.Date to java.sql.Types#DATE.
So I modified AbstractJdbc2Statement.java to accept java.util.Date,then it worked.

Is this good solution?
Please advice.
