> The hashCode generation of {{RestrictionImpl}} currently looks as follows:
> {code}
> public int hashCode() {
> return Objects.hashCode(definition, property);
> }
> {code}
> However, the hashCode of our {{PropertyState}} implementation doesn't include the value. See {{AbstractPropertyState}}:
> {code}
> public static int hashCode(PropertyState property) {
> return property.getName().hashCode();
> }
> {code}
> Consequently the hashCode of the {{AccessControlEntry}} implementation, the validation of ACEs in {{AccessControlValidator}} and the {{AcEntry}} created in the {{PermissionHook}} generates the same hashCode for entries that only differ by the value of a restriction.
