I have a question related to PrepareTransaction, Recoveries and NonDurableMessages We only store the Xid on Journal, if there are PersistentMessages. (which is aways my expecation). That means, if we produce messages on JBM as part of a Distributed Transaction using only NonDurableMessages those XIDs won't be recovered in case of a server crash/restart. Would that cause any issues on the TransactionManager? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174731#...
