Yuriy commented on AMQ-6454:
----------------------------
Gary, thank you for the quick response.
I know that transacted session will work and it does, but in our case there is
an explicit requirement to use a non-transacted JMS session.
By the way this sequence works for other JMS providers like IBM WebSphere MQ,
OpenMQ and WebLogic.
Another issue here is acknowledge() returns successfully, which in general
means that message was acknowledged on JMS server side.
> Message is redelivered after succesfull acknowledge()

> Key: AMQ-6454

> Project: ActiveMQ
> Issue Type: Bug

> JMS message is redelivered after successful call of acknowledge().
> The following methods are invoked:
> Thread1 : Message message = consumer.receive();
> Thread2 : consumer.close();
> Thread1: message.acknowledge();
> All the methods return successfully but the message is redelivered on the
> next receive() call. Note that consumer.close() is typically used to force
> consumer.receive() to return.
> According to JMS specification the scope of message acknowledge() call is
> session (not message consumer):
> https://docs.oracle.com/javaee/7/api/javax/jms/Message.html#acknowledge--
> A simple program to reproduce the bug is attached.
> Observed behavior:
> Message is redelivered.
> Program output:
> ============
> Message sent. Id=ID:comp-63860-1475602285903-1:1:1:1:1
> Message received. Id=ID:comp-63860-1475602285903-1:1:1:1:1. Text=Welcome!
> Message succesfully acknowledged
> Message received. Id=ID:comp-63860-1475602285903-1:1:1:1:1. Text=Welcome!
> Message succesfully acknowledged
> Expected behavior:
> Message should be delivered only once.
