JMS Client acknowledgment sessions: Bug/Clarification

Solution Unverified - Updated -


What is the correct way to force synchronizing message acknowledgments when CLIENT_ACK sessions are used in JMS client of qpid?

Just using "sync_ack='True'" in the connection factory URL does not result in sync acknowledgments
Looks like for the acknowledgments to be synchronous, either the number of unacknowledged messages must be more than prefetch/2 or the qpid.session.max_ack_delay has to be set to zero.
