To clarify, you need to add something like makeAddress to DoSomething:

  Address makeAddress() {
    // Construct the AutoBean
    AutoBean<Address> address = factory.address();

    // Return the Address interface shim
    return address.as();
  }

Then you can change your code to:

    DoSomething test = new DoSomething();
    Person person = test.makePerson();
    person.setName("me");
    person.setAddress(test.makeAddress());
    String json = test.serializeToJson(person);
