@clebertsuconic I think that using a near-to-deprecation feature to solve
the issue can be avoided:
https://github.com/franz1981/activemq-artemis/tree/mmap_ro_2_read_journal
It is a POC that I need @morefuntang feedback to see if it solves the issue
(and it could be applied to ASYNCIO probably) by saving entirely any
`ByteBuffer` allocation while reading journal files.---
