Review Comment:
` <module>artemis-ffm</module>` Isn't really a useful name for the module,
it doesn't really describe what the module is used for or help someone identify
what functionality this might include. Probably should indicate is a libaio
module "artemis-libaio' or some such as the FFM bits is the implementation part
of what its doing, not what it does.

> Proposing a modernization of the artemis-journal module by leveraging the
> Panama Foreign Function & Memory (FFM) API (introduced in JDK 22). This will
