------------------------------------
Summary: JMS client does not assign unique deliveryTag for
messages sent on the same link
Key: QPIDJMS-296
URL: https://issues.apache.org/jira/browse/QPIDJMS-296
Project: Qpid JMS
Issue Type: Bug
Components: qpid-jms-client
Affects Versions: 0.23.0
Reporter: Lorenz Quack
I am creating a {{MessageProducer}} and sending two messages. In the protocol
trace I can see that the two transfers are using the same deliveryTag. This is
in violation of the AMQP1.0 specification. [Section
2.7.5|http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#type-transfer]
states with regards to the {{delivery-tag}}:
bq. Uniquely identifies the delivery attempt for a given message on this link.
This field MUST be specified for the first transfer of a multi-transfer message
and can only be omitted for continuation transfers.
This a snippet of code:
{code}
Connection connection = getConnectionWithPrefetch(0);
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("testQueue");
MessageProducer producer = session.createProducer(queue);
producer.send(session.createMessage());
producer.send(session.createMessage());
{code}
