Subject Re: Recipient list and aggregation when some destinations are unreachable?

Hi

No its better to use the built-in timeouts you have from the JMS
component (such as request timeout if doing request/reply) and the JMS
clients such as from ActiveMQ etc. Then you should not need to use the
timeout setting from receipinent list which is a fallback way and in
this situation adds extra complexity.
