I tried your code. It seems that the Qpid client could ack multiple messages even if the app is only calling message.acknowledge() once. In the traces you can find the the following line which shows the client is accepting 3 messages:
SEND Disposition{role=receiver,first=0,last=2,settled=true,state=Accepted{}}
