In my opinion the documentation is not very clear on this point. It says: > ActiveMQ Artemis will keep a copy of each generated journal file, up to the configured retention period, at the unit chose. On the example above the system would keep all the journal files up to 365 days.
As far as I can tell "each generated journal" file is different from "candidates for deletion." I will fix this soon if nobody else beats me to it first.
