I was initially thinking about the interceptors. But I realized that service
binding providers usually don't add an interceptor to the invocation chain.
Instead, they register a listener to the binding protocol layer to route the
call into SCA. If the service provider receives data from a transport and it
knows the data won't be mutated by reference, it should be able to express
it to help the runtime to bypass PBV.
Thanks,
Raymond

Let me try to propose the following fix:
1) Add new interface such as PassByValueProvider (please help me with a
better name) to the SPI.
public interface PassByValueProvider {
/**
* Indicate if the provider will enforce the pass-by-value semantics
*/
boolean isPassByValueEnforced(Operation op);
}

How about having the interceptors optionally implement that kind of
interface instead of the providers?
