Looks like EventBrokerHolder.getInstance().getTenantId() in RegistrySubscriptionManager of the Event Component is passing -1.
By the way, this seems to be happening at the server start-up. Why does DS clear subscriptions at start-up? Is this to implement some form of non-persistent subscription? If that's so, I believe that the event component already has some concept like that (Amila, Danushka please confirm). Thanks, Senaka.
