[Carbon-dev] NPE occurring because of tenantId passed as -1 to DefaultRealmService.getTenantUserRealm()

[Senaka Fernando]

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.
