Betreff: Re: [platform-dev] Allowing bundles to target Java 17 for 2022-06 release
I agree with Alex to move to Java 17 as minimum supported version for Eclipse 4.27.
 
As committer /project lead on JDT I also think we should move to Java 17 there.
We should not keep supporting Java 11 if we can't even guarantee (due no tests executed) we can run on Java 11.
 
Surely all the downstream projects will need to adopt, but they have a choice: update or keep using older JDT / SDK versions or contribute to platform maintenance.
 
Note regarding JDT ECJ compiler - moving to Java 17 doesn't mean we will stop compilation for older Java versions, but running on Java 17 we still can compile code with target Java 8 etc.

Another note: I miss https://www.eclipse.org/projects/project-plan.php?planurl=http://www.eclipse.org/eclipse/development/plans/eclipse_project_plan_4_27.xml#target_environments
 
We missed to create that plan for 4.27, I've created a PR for that (without exact dates): https://github.com/eclipse-platform/www.eclipse.org-eclipse/pull/26
 
We should add info about supported Java versions there.

Hey everyone,
Our test dependencies (e.g. reddeer), our build tool (tycho) and etc. already require Java 17 thus the whole releng is using Java 17 now with no dependency on Java 11 anymore.
Due to that there are already test bundles that target Java 17 and use Java 17 language features. Feel free to do so even more.
 
As automated Java 11 testing is impossible nowadays I think it's time for us to allow bundles to go to Java 17 BREE after March release.
I welcome constructive discussion which should include how and who is going to take care of Java 11 testing/verification if there is disagreement for this move.
