Adding a Feature to a CXF Client after creating the web service port

Question

I've created the Java classes using wsdl2java from my wsdl file. On client side I'm going to create the port (on which I can call the web service) this way

// Creating Service Class
MyServiceService service = new MyServiceService();
// Creating LoggingFeature
LoggingFeature loggingFeature = new LoggingFeature();
// ...
// Crating WebService
MyService ws = service.getMyService(new WSAddressingFeature(), loggingFeature);
// obtaining the Client
Client client = ClientProxy.getClient(ws);
// Modifying the client timeouts and so on...
// ...

// Call the web service method
ws.callMyWebservice(...);

So I can add Features by creating the web service Class. But is it possible to add a Feature after crating the web service Class?

I've only found a way how to list the active features:

Endpoint endpoint = client.getEndpoint();
List<Feature> features = endpoint.getActiveFeatures()
// ...

But this list is only a view of currently active features. Manipulating this list has no effect.
