Erro estranho com JDBC[RESOLVIDO]

Bom gente, olá a todos primeiramente. Em um dos meus projetos, eu estou usando JDBC puro para a conexão e manipulação do banco de dados. Quando eu vou executar a seguinte classe:

public static Professor loginProf(String matricula, String senha)
    {
        Professor prof = null;
        
        try
        {
            String sql = "SELECT * FROM aluno WHERE matriculaProf = ? AND senha = ?;";
            
            Conexao conex = new Conexao("jdbc:mysql://localhost:3306/mydb",
                    "com.mysql.jdbc.Driver", "root", "alunolab");
            
            Connection con = conex.obterConexao();
            
            PreparedStatement comando = con.prepareStatement(sql);
            
            comando.setString(1, matricula);
            comando.setString(2, senha);
            
            ResultSet resultSet = comando.executeQuery();
            
            if(resultSet.next())
            {
                prof = new Professor(resultSet.getString("matriculaProf"),
                        resultSet.getString("senha"));
            }
            
            resultSet.close();
            comando.close();
            con.close();
            
        }catch ( Exception e)
        {
            System.out.println(e.getMessage());
            e.printStackTrace();
        }
        
        prof = new Professor(matricula, senha);
        return prof;
    }

Aparece a seguinte exceção:
