java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

Problem:
--------
If a PreparedStatement is build without paramters, the clearParameters()
  statement throws a NullPointerException under JDK1.3, it works fine with
JDK1.2.2.

The bug was encounted using enhydra (v3.1) DO objects (Data Layer). The enhydra
framework makes the call to clearParameters() on the second time the query is
executed.


Source Code:
------------
import java.sql.*;
import java.io.*;

public class JDBCTest
{
    final static String URL = "jdbc:odbc:SQLServer";
    final static String STMT ="Select * from board";

    public static void main(String[] args) throws Exception
    {

        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();

        Connection conn = DriverManager.getConnection(URL,"","");
        PreparedStatement stmt = conn.prepareStatement(STMT);

        stmt.clearParameters();

        stmt.close();
        conn.close();
    }
}


Error message:
--------------
Exception in thread "main" java.lang.NullPointerException
        at sun.jdbc.odbc.JdbcOdbcPreparedStatement.clearParameters
(JdbcOdbcPreparedStatement.java:1012)
        at JDBCTest.main(JDBCTest.java:22)
