---------------------------------
Assignee: Freeman Fang
> synchronized store and getMessages of JmsPullPoint would cause deadlock
> -----------------------------------------------------------------------

> Key: CXF-7145

> Project: CXF
> Issue Type: Bug
> Components: Services
> Reporter: Freeman Fang

>
> The JmsPullPoint would be accessed by both the producer client and consumer
> client, currently the whole store(used by producer) and getMessages(used by
> consumer) method was synchronized. For some flow control scenario[1], the
> {code}
> producer.send(message);
> {code}
> in store method would be blocked if the jms queue exceed some certain size,
> in this case the getMessages method never get chance to be invoked to
> decrease the queue size which cause deadlock.
> Actually in the methods only the session is critical resource which should be
> synchronized, so we should synchronize the session only to avoid this deadlock
