AT:

• The RuntimeService provides a method for triggering message event subsciptions, providing

• message event name
• a Map of correlation parameters
• a Map of process variables
• ...

• The expected behavior is that the implementation finds the corresponding execution (taking into account the correlation set) and triggers that execution. The method may also start a new process instance.

• If no event subscription for the provided message event name can be found an Error is returned
• If multiple event subscriptions for the provided message event name + correlation can be found an Error is returned

• Nice documentation can be found in the BPMN Implementation Reference

CONSIDER:

• the actual correlation logic may be abstracted using a configuration interface (MessageCorrelationHandler ?) so that users can plug in custom correlation logic
