Bean constraint validation causes stackoverflow

Question

Trying to make a contraint validator to check whether an e-mail is available for being used for registration using an annotation.

Hibernate keep calling validate() method to validate the entity which causes a stackoverflow exception.

@Component
public class ValidatorAddingCustomizer implements HibernatePropertiesCustomizer {

    private final ObjectProvider<javax.validation.Validator> provider;

    public ValidatorAddingCustomizer(ObjectProvider<javax.validation.Validator> provider) {
        this.provider = provider;
    }

    public void customize(Map<String, Object> hibernateProperties) {
        Validator validator = provider.getIfUnique();

        if (validator != null) {
            hibernateProperties.put("javax.persistence.validation.factory", validator);
        }
    }
}

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = UniqueCompteEmailValidator.class)
@Target({ ElementType.TYPE })
public @interface UniqueCompteEmail {

    String message() default "{com.mssmfactory.bacsimulator.uniquecompteemail.message}";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

public class UniqueCompteEmailValidator implements ConstraintValidator<UniqueCompteEmail, Compte> {

    @Autowired
    private CompteRepository compteRepository;

    @Override
    public boolean isValid(Compte value, ConstraintValidatorContext context) {
        if (value != null) {
            System.out.println("here is the value: " + value);

            Compte persistedCompte = this.compteRepository.findByEmail(value.getEmail());

            System.out.println("compte: " + persistedCompte);

            return persistedCompte == null || value.getId() == persistedCompte.getId();
        } else
            return false;
    }
}

@Repository
public interface CompteRepository extends JpaRepository<Compte, Integer> {

    public Compte findByUsername(String username);

    public Compte findByEmail(String email);
}

here is the value:
