I think that pure Java proxies doesn’t have such limitation:

Object proxy = Proxy.newProxyInstance(null, new Class[] { }, handler);

System.out.println(Arrays.toString(proxy.getClass().getInterfaces())); // returns []

In this there way there is no interface involved. Maybe Java API should have clarification for that (interfaces – the list of interfaces for the proxy class to implement).
