> In order to preserve the symmetry of equals the AbstractCollectionDecorator shall not forward calls to equals and hashcode to the decorated collection.
> The test for equality usually also includes a test for the specific interface, e.g. List, which the collection decorator does not implement.
> The relevant sub-classes like AbstractListDecorator can delegate the calls to safely fulfill the Collections contract.
