> The {{countBeforeFull}} method that is part of {{Subscription}} is supposed to return the number of messages that the subscription can accept before it is full.  This works fine for Durables and Queues (Prefetch subscriptions) where the value is a positive value when it can accept more messages.  Usually the value will report the size of prefetch minus any prefetch extension and dispatchedQueueSize.
> However, for a {{TopicSubscription}} this value is reversed and it is subtracting prefetch from dispatchedQueueSize.  For example, if the prefetch policy is set at 1000, this method will report "-1000" when calling countBeforeFull.
