Mark Combellack updated TUSCANY-1856:
-------------------------------------

    Attachment: ConversationIDExtensionPoint.patch

The attached patch contains:

ConversationIDFactoryExtensionPoint
  - Interface for the Conversation ID Extension Point

DefaultConversationIDFactoryExtensionPoint  
  - Default implementation of the ConversationIDFactoryExtensionPoint that uses 
UUID.randomUUID().toString() to create the Conversation ID

DefaultConversationIDFactoryExtensionPointTestCase
  - Simple test case for DefaultConversationIDFactoryExtensionPoint


The rest of the file modifications are to update the rest of the Tuscany code 
to use the new Extension Point.


> Add Create Conversation ID Factory Extension Point so code for creating 
> Conversation IDs is not duplicated throughout code base

> Currently in Tuscany, we use UUID to create Conversation IDs in various 
> points of the code in various modules. For examples of this, see [1].
> The code is all basically the same:
>       UUID.randomUUID().toString();
> The above common code should be extracted out into an Conversation ID 
> Extension Point so it can be shared throughout the code base.
> As an added benefit, this change will allow different implementations of the 
> Extension Point to be plugged in. For example, when Tuscany is extended to 
> become a distributed runtime, it may be desirable to add the host name to the 
> Conversation ID. This can be achieved by adding a different implementation of 
> this Extension Point
