refactor this code snippet possible bug

[fredsonchaves07]

    private void validateLoginDTO(LoginDTO loginDTO) {
        if (loginDTO == null)
            throw new EmailOrPasswordIncorrectException();
        if (loginDTO.getEmail() == null || loginDTO.getPassword() == null)
            throw new EmailOrPasswordIncorrectException();
        if (!emailAlreadyExist(loginDTO.getEmail()))
            throw new EmailOrPasswordIncorrectException();
        if (!isEmailPasswordMatch(loginDTO.getEmail(), loginDTO.getPassword()))
            throw new EmailOrPasswordIncorrectException();
        if (!userIsConfirmed())
            throw new UnconfirmedUserException();
    }

if the order of isEmailPasswordMatch with userIsConfirmed is changed, a bug may occur
