bug with javax.jms.Session.AUTO_ACKNOWLEDGE in ActiveMQ ?

When I use createQueueSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE)
the Messages are not removed from the Queue.

When I use createQueueSession(true, javax.jms.Session.AUTO_ACKNOWLEDGE) and
call getSession().commit() in the onMessage Method

the Messages are removed from the Queue.

optimizeAcknowledge now off by default

Note that a workaround is to disable optimizeAcknowledge - e.g.

tcp://localhost:61616?jms.optimizeAcknowledge=false
