>             Project: Tuscany
>          Issue Type: Bug
>          Components: Java SCA Axis Binding Extension, Java SCA Core Runtime
>    Affects Versions: Java-SCA-1.0
>         Environment: All
>            Reporter: Simon Nash
>            Assignee: Raymond Feng
>             Fix For: Java-SCA-1.0

>
> The Axis2 service binding dispatch code creates a cloned runtime wire to pass the callback endpoint, callback ID, and conversation ID.  This creates new RuntimeWireImpl, RuntimeWireInvoker, and Message objects for every dispatch.
> A small change to the SPI interface will eliminate the need to create the RuntimeWireImpl and RuntimeWireInvoker objects.  The binding extension dispatch code can create a Message object and store the callback endpoint, callback ID, and conversation ID in this object.  Instead of the bindng extension dispatch code calling
>    wire.invoke(op, args)
> on the cloned wire, the args can be set into the body of the Message object along with the other information and the binding dispatch code can call
>    wire.invoke(op, msg)
> on the uncloned wire.  A method with this signature would also be added to RuntimeWireInvoker and called as a "pass through".
> The dispatch code in RuntimeWireInvoker can use the Message object that was passed in instead of creating a new one and populating it from the cloned RuntimeWire.
> This needs to be done for 1.0 as it changes the contract between the binding extension code and the core runtime.
