There used to be a connection URL parameter "sync_ack" which could have been used to define whether acknowledgments should be sent synchronously or asynchronously. Is this parameter still supported?
It seems to me that whatever value I give to it, it always syncs after every acknowledgements. From digging through the code it seems to me that it is reflected only when I use AUTO_ACKNOWLEDGE mode, but not when I acknowledge the messages manually. I also noticed that the "Using the Qpid JMS client (AMQP 0-10)" document on the website ( https://qpid.apache.org/releases/qpid-0.32/programming/book/QpidJMS.html) is not updated since 0.32 release. It is missing for the 6.0.x releases - it looks like it disappeared with the independent Java releases. I guess that is probably not intentional. Thanks & Regards Jakub
