Hans Bausewein commented on AMQ-1950:
-------------------------------------
I don't know, what you mean. StandaloneApp is my handy client. (I think)
It works by posting a message to 'queue.A' with the ActiveMQ console (or anyway
you like, of course) with a reply queue (I use "queue.ReplyA").
Then the first message handler (handler A) forwards the message to 'queue.B'
to which the second message handler is listening.
The second message handler replies to the first through the reply queue (set by
handler A).
The first (handler A) replies to the reply you've specified in the first
request.

> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.2.0
> Environment: JBoss 4.0.5 GA with ActiveMQ resource adapter and Java
> 1.6 update 7
> I used the ActiveMQ 5.2.0 RC1 from 10th september.
> Reporter: Hans Bausewein
> Assignee: Gary Tully
> Fix For: 5.3.0

> Attachments: activemqjee-0.0.4-src.tar.gz, amq-1950.patch.2.txt,
> deadlock.txt

>
> The deadlock occurs on the slave after sending some 30 messages. Sending a
> few at a time works fine.
> The test application is a MessageDrivenBean that sends a message to another
> MDB with a temporary reply queue.
