[jira] [Created] (ISIS-1028) Create Event Bus Service based on Axon

Oscar Bou created ISIS-1028:
-------------------------------

             Summary: Create Event Bus Service based on Axon
                 Key: ISIS-1028
                 URL: https://issues.apache.org/jira/browse/ISIS-1028
             Project: Isis
          Issue Type: New Feature
          Components: Core
    Affects Versions: core-1.8.0
            Reporter: Oscar Bou
            Assignee: Oscar Bou
             Fix For: core-1.9.0


Current Guava based implementation queues events, and that implies changes to the execution flow.

Axon Event Bus implementations simply dispatches events as soon as are posted.

That way, logic when dispatching events is always the same (immediate dispatching when posted), without depending on an Event being dispatched when no other Event is dispatching (so its Event Handlers would be invoked immediately) or when other Event is currently being dispatched (in which case Guava would queue it instead of immediately dispatching).
