I am curious whether oepnHAB Event mechanism follows the OSGI Event Admin Service. Can it be configured as ordered or not ordered for receiving events? More specifically, if I have a component which is registered under EventSubscriber Service, can I configure this component to receive ordered or unordered events?
No.
So I guess that openHAB is using Felix, and the default configuration is that all events emitted from single working thread is ordered. Is that correct?
