---------------------------------------
Hi Christian
We discussed this issue with Ron on #cxf.
It seems that what Ron suggested is doable. JMS Continuation is really a light
weight way to decouple a (JMS request) thread from an (application) worker
thread, please see
http://svn.apache.org/repos/asf/cxf/trunk/rt/transports/jms/src/main/java/org/apache/cxf/transport/jms/continuations/,
JMSDestination creates a new continuation instance per in message.
users can also get (Jetty) HTTP and JMS requests and suspend them using the
same api.
JMSContinuationProvider adds new continuations to a (concurrent) list, while
JMSContinuation removes itself when it expires or get resumed.
I was thinking that if we passed a JMSDestination.listener and JMSConfiguration
to JMSContinuationProvider and JMSContinuation, then we'd be able to set a
number of concurrentConsumers on a listener as appropriate
Does it make sense ? thanks...

> Key: CXF-2002
> URL: https://issues.apache.org/jira/browse/CXF-2002
> Project: CXF
> Issue Type: Improvement
> Components: Transports
> Affects Versions: 2.0.9, 2.1.3, 2.0.10
> Reporter: Ron Gavlin
> Assignee: Christian Schneider
> Fix For: 2.2
>
>
> Currently, the server-side async jms transport has no mechanism to throttle
> consumption of incoming messages. This becomes problematic in scenarios where
> a large backlog of messages exists on the input queue. In this case, it is
> likely that the cxf server will overload its internal work item queues
> resulting in problems. A dynamic throttling mechanism on the async jms server
> is required to avoid this problem.
