--------------------------------------
Hmm, 4.2.0 is current release. 4.3.0 is next release. Is it OK for you?

> On topic loss, InMemorySubscriptionManager currently does not clear
> top2sub2seq. The intent is to allow readSubscription to get the information
> there. This introduce dependency outside the class, evidence is that general
> ReleaseOp has to use a boolean parameter which targets this implementation
> detail. Further, this prevents Acquire-topic to notify listeners
> (notifyFirstLocalSubscribe is not called) of first subscription to act
> appropriately.
