Vladimir Tsvetkov commented on CAMEL-5309:
------------------------------------------
Is .threads(10) makes more sense if the route is:
{code}
from("direct:processStateStart")
.setExchangePattern(ExchangePattern.InOut)
.to("activemq:queue:tasksQueue?replyTo=processedIndecesQueue" +
"&replyToType=Exclusive" +
"&requestTimeout=" + PROCESS_INDEX_TIMEOUT)
.threads(10)
.to("log:REPLY?level=DEBUG")
.routeId("route-002")
{code}
As to how I reported the issue, I've tried to provide the minimum information
that can describe the issue, and I was waiting to add more (e.g. a unit test)
upon request.

> Key: CAMEL-5309
> URL: https://issues.apache.org/jira/browse/CAMEL-5309
> Project: Camel
> Issue Type: Bug
> Components: camel-activemq, camel-jms
> Affects Versions: 2.9.2
> Environment: Java 1.6, ActiveMQ 5.6-SNAPSHOT (used in-memory within a
> Spring application)
> Reporter: Vladimir Tsvetkov
> Assignee: Claus Ibsen
>
> When I first instantiate the following route, it works as expected. The
> Replies that come have the right correlation ids, just as Camel has assigned
> them.
> {code}
> from("direct:fetchStateStart")
> .setExchangePattern(ExchangePattern.InOut)
> .to("activemq:queue:tasksQueue?replyTo=completionsQueue" +
> "&replyToType=Exclusive" +
> "&requestTimeout=" + FETCH_INDEX_TIMEOUT)
> .threads(10)
> .routeId("route-001");
> {code}
> When this route completes, it is stopped and removed from the camel context.
> When a similar route is instantiated:
> {code}
> from("direct:processStateStart")
> .setExchangePattern(ExchangePattern.InOut)
> .to("activemq:queue:tasksQueue?replyTo=completionsQueue" +
> "&replyToType=Exclusive" +
> "&requestTimeout=" + PROCESS_INDEX_TIMEOUT)
> .threads(10)
> .routeId("route-002");
> {code}
> Half of the replies come as expected, while the other half results in the
> following warning: *Reply received for unknown correlationID*.
> A workaround for this issues is to use a different *ReplyTo*-queue for each
> new instantiation of a similar route.
> E.g. for the second route, it'll work if:
> {code}
> from("direct:processStateStart")
> .setExchangePattern(ExchangePattern.InOut)
> .to("activemq:queue:tasksQueue?replyTo=processedIndecesQueue" +
> "&replyToType=Exclusive" +
> "&requestTimeout=" + PROCESS_INDEX_TIMEOUT)
> .threads(10)
> .routeId("route-002");
> {code}
