Hello.
I'm experimenting with the ComponentProvider interface and attempting
to return a dynamic proxy as the instance from those "getInstance"
methods. The root resource class implements a method on an interface
that is annotated with @GET. The dynamic proxy is applied to this
interface and eventually delegates its logic to the implementation
method.
However, it appears that Jersey is invoking the *implementation*
method, not the interface method, which actually defines the REST
interface (since that's where the annotations reside). Is this by
design?
