Problema com toString | Spring Data JPA: Repositórios, Consultas, Projeções e Specifications

Quando eu coloco escrevo o toString tenho o erro a seguir, isso ocorre apenas com o toString quando n tem ele imprime o endereço de memoria sem erro.

repare que ele esta fazendo o select na tabela da forma correta

Hibernate: 
    select
        cargo0_.id as id1_0_,
        cargo0_.descricao as descrica2_0_ 
    from
        cargos cargo0_

Estou escrevendo o método visualizar dessa forma:

    private void visualizar() {
        Iterable<Cargo> cargo = cargoRepository.findAll();
        cargo.forEach(cargos -> System.out.println(cargos));
    }

Classe Application.java a "view" esta dessa forma, pode ser um problema nessa classe
