Statement.getResultSetType () seems failed to change the result set type

@Test

public void test() throws SQLException {

    Connection con = null;

    Statement stmt = null;

    ResultSet rs = null;

    con = DriverManager.getConnection("jdbc:mariadb://localhost:3366/test69?user=user&password=password");

    stmt = con.createStatement(1004, 1008, 2);

    stmt.addBatch("DROP TABLE IF EXISTS table0_0;");

    stmt.addBatch("CREATE TABLE table0_0(id INT AUTO_INCREMENT PRIMARY KEY,value INT);");

    stmt.addBatch("INSERT INTO table0_0 VALUES(1, -179653912)");

    stmt.addBatch("INSERT INTO table0_0 VALUES(2, 1207965915)");

    stmt.executeBatch();

    stmt.executeUpdate("INSERT INTO table0_0 (value) VALUES(667711856)", Statement.RETURN_GENERATED_KEYS);

    rs = stmt.getGeneratedKeys();

    System.out.println(stmt.getResultSetType()); // 1004

    System.out.println(rs.getType()); // 1003

}
