> Should we switch our modules to Jigsaw modules?
- Now that attributes serialization no longer relies on FST (and no longer
allows arbitrary deserialisation) we *could* try to better enforce Java modules.
> Should we maintain a JDK11 version in parallel for letting time for everybody
> to do the switch?

James is still a moving project. We can announce that James 3.8.x is the last
Java 11 compatible branch, and offer support for it.
> can refactoring things little by little after (like switching to records for
> POJOs for example)
Huge +1 for record adoption!

> Key: JAMES-3961

> Issue Type: Improvement
> Reporter: René Cordier
> Priority: Major
> Fix For: 3.9.0
>
>
> The community seems in favor of adopting JDK 21 and migrating the code base
> to it. Multiple reasons for it:
> * JDK 11 reached officially EOLÂ
> * JDK 21 is the latest LTS
> * multiple new features like records (bye bye boilerplates on POJOs),
> pattern matching, better GC, better thread management, ...
> Few things to keep in mind as well:
> * should we switch our modules to Jigsaw modules?
> * should we maintain a JDK11 version in parallel for letting time for
> everybody to do the switch?
> How:
> * ADR explaining the change
> * switch the JDK to 21 in the code base
> * modify the code to get a green build with minimal changes first
> * update documentation accordingly
> * can refactoring things little by little after (like switching to records
> for POJOs for example)
