I placed the code in jira: https://issues.apache.org/jira/browse/JCR-1100. I think there is a lot of room to make this better. Here is an example test case I wrote with our data:

       JcrRepository repo = getRepository();
       Feature feature = new FeatureImpl("test feature mixin");
       feature = (Feature)repo.add(feature);

       feature = (Feature)feature.addMixin(new EngineImpl());
       Engine engine = (Engine)feature;
       engine.setConfiguration(Engine.V_CONFIGURATION);
       engine.setFuelType(Engine.UNLEADED_FUEL);
       engine.setHorsePower(200);
       engine.setHorsePowerRPM(10);
       repo.save(feature);

       Object obj = repo.forPath(feature.getPath());
       assert obj instanceof Engine;

Note in this example there are four java files: Feature (interface), FeatureImpl (class), Engine (interface), Engine (class)...

I think this would be a great idea, I implemented something similar for
OCM using cglib mixin proxies to provide mixin support at run time.
