In all current releases, org.apache.camel.component.jms.EndpointMessageListener.onMessage() has the following logic (line 90 in 1.6.0 code):
This logic should also respect ExchangePattern of the exchange, so I propose a change to:
This change allows a processing pattern where the route may change the ExchangePattern using methods like RouteBuilder.inOnly() to switch the MEP at will so that the reply is send at a later time (true asynchronous exchange). This processing pattern is particularly useful for integrating long running services. For example,
The flaw of the current logic makes it impossible to do true asynchronous exchange, because 1) it does not respect the ExchangePattern; 2) if property "disableReplyTo" is used, the "org.apache.camel.jms.replyDestination" property will not be set (see method createExchange in the same file), thus downstream cannot find the reply destination.
The proposed change can also deprecate the disableReplyTo property and put the MEP concept into good use.
