Subject [jira] [Created] (AMQ-3543) STOMP connector: unexpected reply-to value for remote temporary topic

STOMP connector: unexpected reply-to value for remote temporary topic
---------------------------------------------------------------------

                 Key: AMQ-3543
                 URL: https://issues.apache.org/jira/browse/AMQ-3543
             Project: ActiveMQ
          Issue Type: Bug
            Reporter: Christopher Barrow
            Priority: Minor


The reply-to header on a MESSAGE frame resulting from the sending of a message (SEND) with
the reply-to header set to a temporary topic is in the form /temp-topic/<local-temp-topic-name>
rather than the expected 
/remote-temp-topic/<system_generated_name>

This only happens when the same connection is used for sending and receiving messages. When
a temporary queue is used, the reply-two appears as /remote-temp-queue/xxx as expected. So
even if one takes the position that it is reasonable for the local name to be used given that
everything is on the same connection, there is an inconsistency between the topic and queue
cases. For our purposes we would prefer that the remote form be used always.

Test case for the underlying ActiveMQ bug is attached: StompRemoteTempTopic.java

To reproduce, drop this file into $ACTIVEMQ_HOME/example/src, edit build.xml in the example
directory to add the following:

<target name="bug" depends="compile" description="Runs test case for replyTo TempTopic
bug">
<echo>Running a Stomp example</echo>
<java classname="StompRemoteTempTopic" fork="yes" maxmemory="100M">
<classpath refid="javac.classpath" />
<jvmarg value="-server" />
</java>
</target>

and run by issuing the command "ant bug". Output is as follows:

[echo] Running a Stomp example
[java] =====================================================
[java] Test run using temporary topic
[java] -----------------------------------------------------
[java] Sending request message: SEND with reply-to=/temp-topic/2C26441740C0ECC9tt1
[java] Received request message: MESSAGE with reply-to=/temp-topic/2C26441740C0ECC9tt1
[java] Response MESSAGE received
[java] =====================================================
[java] Test run using temporary queue
[java] -----------------------------------------------------
[java] Sending request message: SEND with reply-to=/temp-queue/2C26441740C0ECC9tt1
[java] Received request message: MESSAGE with reply-to=/remote-temp-queue/ID:ChrisBarrow-lap-61815-1318539910206-4:6:1
[java] Response MESSAGE received

This makes it easy to see that for the queue case the reply-to is set to the remote temporary
queue but for the topic case the local temporary topic is specified.
