Issue #4: Dependency Reinjection

http://www.osoa.org/jira/browse/JAVA-4

There are two outstanding sub-issues:
A) does a reference represent the wire or the wire target (i.e. does it get invalid if the target changes, or is it a "smart" proxy)?
B) does the component context reflect wiring changes during the life time of the component scope?



Regarding the (A) Ron, Peter, and Henning came up with the following proposed assertions: 

1. Services have an address: Service Component Services have an SCA URI, otherwise bindings provide a URI or some equivalent addressing data.
2. Service reference instances are a client view to a service address: It consists of the service address and (if available) a conversation handle (e.g. an ID, a proxy) and interface information.
3. The address and interface association does not change over the life time of a service reference. An exchange (re-deployment) of the addressed service's implementation SHOULD not invalidate a Service reference instance. Technical constraints may however lead to a de-facto invalidation of service reference instances (e.g. cannot consume previously handed out data).

Or, in one paragraph: 

Services have an address, which can be an SCA URI in the case of a service component service or some other addressing data provided by a binding declaration. A service reference instance is a client view to a service address. It consists of the service address and (if available) a conversation handle (e.g. an ID, a proxy) and interface information. The address and interface association does not change over the life time of a service reference instance. An exchange (re-deployment) of the addressed service's implementation SHOULD not invalidate a Service reference instance. Technical constraints may however lead to a de-facto invalidation of service reference instances (e.g. cannot consume previously handed out data).
