Description

In an environment using OpenWire NMS clients, after the consumer reconnection, we see that messages get prefetched out to the consumer up to its default limit (1000); however, after the client acks all the messages (and the broker shows 1000 messages acked), the broker still reports the consumer is waiting on credits and reports current credits as NULL:

DEBUG [org.apache.activemq.artemis.core.server.impl.ServerConsumerImpl] ServerConsumerImpl [id=0, filter=null, binding=LocalQueueBinding [address=XXXX, queue=QueueImpl[name=XXXX, postOffice=PostOfficeImpl [server=ActiveMQServerImpl::serverUUID=XXXX], temp=false], filter=null, name=XXXX, clusterName=XXXX]] is busy for the lack of credits. Current credits = null Can't receive reference Reference[45099938419]:RELIABLE:CoreMessage...

Looking at a heap from the affected broker, the currentWindow for the consumer is "0" though there are no message references in deliveringRefs.
