Subject [jira] [Resolved] (CAMEL-7897) Camel consumes & discards activemq messages after suspension
Date Sun, 15 Feb 2015 16:36:12 GMT


Claus Ibsen resolved CAMEL-7897.
    Resolution: Won't Fix
      Assignee: Claus Ibsen

There is always a window of opportunity that the jms consumer pickup new messages while suspending.

You can set acceptMessagesWhileStopping=true and process the messages instead of rejecting

Then when the suspending is complete new messages stats on the queue.

> When used with a PooledConnectionFactory, a Camel Route that consumes via JMS from an
ActiveMQ endpoint will read one extra message and simply discard it *after* it has completed
suspension, if that message is sent within a second of suspension being completed.
> See attached test case.
> As far as I can tell this is because nothing interrupts the taskExecutor on DefaultMessageListenerContainer
when a route is suspended.
> Expected behaviour - once a route is suspended, any messages sent to the queue from which
it consumes should remain on that queue.
