1. Accepting new issues:

NEW ISSUE: Callback Simplification

RAISER: Michael Rowley

http://www.osoa.org/jira/browse/JAVA-25

ISSUE 26: Description of interface.java is needed

RAISER: Dave Booz

http://www.osoa.org/jira/browse/JAVA-26

2. Issues discussion

JAVA-4: Dependency Reinjection (REPRISED)

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

Although resolved, the resolution may need the following addendum:

Callback references MUST NOT be reinjected. If a conversational-scoped
service implementation is invoked by multiple clients using the same application-generated
conversationID, any injected callback reference will refer to the client
that made the initial invocation. A reference to the client that made the
current invocation can be obtained by using the RequestContext API.

The email that describes the need for this is here:

michael beisiegel: 1st of links shows proposal

michael beisiegel: This proposal aims to simplify
using asynchronous communication in   

the SCA Java programming model by:

1. Eliminating callback objects.

    - Removing ServiceReference.get/setCallback()

2. Removing the ability for service providers to get callback IDs.

    - Moving CallableReference getCallbackID() to ServiceReference)

3. Saying callback IDs are irrelevant in conversations.

    - Making ServiceReference.setCallbackID(Object id) illegal
and

      ServiceReference.getCallbackID() (assuming #2) return
null for

      conversational interactions.

4. Removing the distinction between stateless and conversational

    callback interfaces.

     - Removing the ability to specify conversational on callback

       Interfaces.
