Raul Kripalani updated CAMEL-5465:
----------------------------------
Summary: JMS Reply Manager is shared across producers for the same endpoint
(was: JMS Reply Managers should remove correlation earlier)
> JMS Reply Manager is shared across producers for the same endpoint
> ------------------------------------------------------------------
>
> Key: CAMEL-5465
> URL: https://issues.apache.org/jira/browse/CAMEL-5465
> Project: Camel
> Issue Type: Bug
> Components: camel-activemq, camel-jms
> Affects Versions: 2.8.6, 2.9.2
> Reporter: Raul Kripalani
> Assignee: Raul Kripalani
> Fix For: 2.9.3, 2.10.0
>
>
> When handling synchronous invocations, both JMS reply managers
> {{TemporaryQueueReplyManager}} and {{PersistentQueueReplyManager}} remove the
> correlation too late.
> {{ReplyManager.handleReplyMessage}} handles the reply triggering the
> continuation of the remaining route logic, which may as well contain yet
> another JMS invocation to exactly the same destination, e.g.:
> {code}
> <route>
> <from uri="direct:hello" />
> <inOut uri="activemq:queue:test" />
> <inOut uri="activemq:queue:test" />
> </route>
> {code}
> As a result, the correlation is not removed from the CorrelationMap until the
> asynchronous dispatch to the second endpoint has finished and the stack
> unwinds.
> What's worse is that, due to Camel's re-use of endpoints, both producers are
> represented as exactly the same Endpoint instance, sharing *the same
> ReplyManager and CorrelationMap*.
> So during the dispatch to the second endpoint, the correlation is overwritten
> in the CorrelationMap but, immediately after, the first endpoint removes the
> correlation anyway!
> Since correlation ID are dragged on (see CAMEL-5390), the route will fail,
> providing a bad out-of-box experience for such a simple use case.
