Description

The above EMS log entry can be seen, if message tracing is enabled on the specific destination and the consumer is destroyed by the client application before it acknowledges the message. 

Under normal coding "invisible rules", the message would have to be acknowledged before the consumer is closed, in order to not see a similar EMS log entry, this is expected behaviour and it is not a defect.
