Hi, I'm looking into this one and found that camel-sjms is using individual JMS sessions for each endpoints. https://issues.apache.org/jira/browse/CAMEL-9606
As I commented, it causes inconsistency if the process is terminated in the middle of processing those synchronizations, so it doesn't make much sense in terms of atomicity. I think it would be better to add an option to share a single JMS Session among SJMS endpoints, and if it's disabled we can just commit those immidiately for each producer/consumer (i.e. remove synchronization usage). And I'd like to enable this option by default as I don't see any situation that they don't want to share the Session, transacted=false would be enough. Thoughts? If it sounds OK for you guys, I'll make a PR for it. Thanks, Tomo -- Tomohisa Igarashi mailto:tm.igara...@gmail.com
