Ok, sorry, got confused a bit. Indeed ConsumeJMS is using auto-ack at the moment, hence can suffer from the same problem as GetJMS. However, the designed of this new JMS support definitely provides for exposure of ACK and other properties to the end user. Please raise JIRA and we’ll take care of it.
