How temporary are the temporary queues in Camel Request/Reply pattern?

[emb]

Do Temporary Queues get deleted at all? Or are the destinations valid
while the route is running?

Suppose we have a simple route like so;
<route>
  <from uri="timer:foo?period=5000"/>
  <inOut uri="activemq:queue:Test.Queue"/>
</route>

Suppose also, that the activemq endopoint times out. In other words,
the replier took longer than the timeout to reply.

Would you expect the replier to successfully place a message in the
temporary queue?

We found that the temporary destination stay alive and ignores
incoming messages with incorrect correlation ids. This may be a
desirable behaviour, however if the messages are critical dropping
them or ignoring them is perhaps not the best option. Our replier was
designed to fall back on a different queue if the temporary
destination was deleted.

What do my fellow camel users do in this scenario?

The JMS API to create a temporary queue is being used.
And to my understanding the temp queue is valid as long the JMSSession is.
