Error connecting to MySQL database in Java

Connection code:

package br.bent.jdbc;

import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Connection;

public class Conexao {

    private static Conexao conexao;

    public static Conexao getInstance(){
        if (conexao == null){
            conexao = new Conexao();
        }
        return conexao;
    }
    public Connection getConnection() throws ClassNotFoundException,SQLException{
        Class.forName("com.mysql.jdbc.Driver");

        return DriverManager.getConnection("jdbc:mysql://localhost:3306/consultab","root","root");
    } 
    public static void main(String[]args){
        try{
        System.out.println(getInstance().getConnection());
        } catch (Exception e){
            e.printStackTrace();
        }
    }

Resultant error:

Another detail I did not mention, is the following I'm using mysql workbench 6.3, and the connector version is 5.1 of this error.
