Gary Tully commented on AMQ-6454:
---------------------------------
yes, that would be in the intent. When the broker url is: host:port?jms
ignoreConsumerCloseOnClientAck=true
the close would be ignored, session close will call close on all consumers.
Then the close check in the message.acknowledge would pass and the ack would
work.
> Message is redelivered after succesfull acknowledge()

> Key: AMQ-6454
> URL: https://issues.apache.org/jira/browse/AMQ-6454
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.14.1
> Reporter: Yuriy
> Attachments: activemq-bug.zip
>
>
> 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.
