    Returns the current number of consumers active at the time this advisory was sent. Note that this is not the number of consumers active when the consumer started consuming. It is usually more vital to know how many consumers there are now - rather than historically how many there were when a consumer started. So if you create a ConsumerListener after many consumers have started, you will receive a ConsumerEvent for each consumer. However the getConsumerCount() method will always return the current active consumer count on each event.
