because in bool AssocRules::allowAssociation() starting with line 212ff there
is code to exclude mutual compositions, which fails to detect this case.

    case Uml::AssociationType::Composition:   // can't have mutual composition
    case Uml::AssociationType::Containment:   // can't have mutual containment
    case Uml::AssociationType::Generalization://can have many sub/super types
but can't sup/sub each
        foreach (AssociationWidget * assoc, list) {
            if((widgetA == assoc->widgetForRole(Uml::RoleType::A) ||
                        widgetA == assoc->widgetForRole(Uml::RoleType::B))
                    && assoc->associationType() == assocType)
                return false;
        }
        return true;
        break;
