Aslında yaptığım komplex birşey değil ama bu hatayı alıyorum listimi döngüye sokuyorum ve gerekli şart uyduğunda remove yapıp çıkmasını istiyorum.

Methodum :

 public String masterCikisSepet() {
        String randomSayi = (String) FacesContext.getCurrentInstance().
                getExternalContext().getRequestParameterMap().get("randomSayi");
        System.out.println(randomSayi);
        Iterator<DbasMaster> i = uruGiris.listIterator();
        while (i.hasNext()) {
            DbasMaster y = i.next();
            if (y.getRadomSayi().equals(randomSayi)) {
                System.out.println("Adet Sayisi : " + y.getAdet());
                uruGiris.remove(y);
            }
        }

        return PageNavigator.faturaGiris();

    }

Hata :

Sorunu bu şekilde hallettim arkadaşlar :

public String masterCikisSepet() {

        String randomSayi = (String) FacesContext.getCurrentInstance().
                getExternalContext().getRequestParameterMap().get("randomSayi");
        System.out.println(randomSayi);

        Iterator<DbasMaster> i = uruGiris.listIterator();
        while (i.hasNext()) {
            DbasMaster y = i.next();
            if (y.getRadomSayi().equals(randomSayi)) {
                System.out.println("Adet Sayisi : " + y.getAdet());
                i.remove();    // iterator'den gelen o anki nesneyi remove ettim
            }
        }
        return "faturagiris";

    }
