You mean, describe what I do that causes this? Or the specific code/files that does this? I can describe the scenario for sure, tho I cannot do the latter.
1. Service X will store data into DB, and will send a message to ActiveMQ. 2. ActiveMQ on machine Y receives the message, and processes it, and sends the message out. 3. Service X will receive that message, processed on machine Y, and do some processing on it. 4. Service X will finally try to commit the data originally stored into the DB in step 1. What should've happened is the following: 1. Service X will store data into DB, and will send a message to ActiveMQ. 2. Once sending the message is successful, it will commit the data to the DB, and make the message receivable by the listeners on the queue. 3. ActiveMQ on machine Y receives the message, and processes it, and sends the message out. 4. Service X will receive that message, processed on machine Y, and do some processing on it. For some reason, when I use MySQL as the message persistence using Jencks to make DB store and message sending transactional, it all works well as expected. But when I *only* switch the message persistence mechanism within ActiveMQ's config, it starts to behave wrongly.
