ProxyFactory doesn't generate correct URLs for subresource locators in JBoss EAP 6.x

Issue

Subresource locators works on server side, however it doesn't work as expected when generating the client proxies with ProxyFactory. The following code can be used to reproduce the issue:

Interface:

        @Path("resource")
        interface Resource{
                @Path("sub")
                public SubResource go();    
        }   

        interface SubResource {
                @GET
                public String goSub();
        }

Calling the sub resource locator:

Resource resource = crf.createProxy(Resource.class);
resource.go().goSub();

Will generate a GET on /sub, when it should generate a get on /resource/sub.
