Completed pruning of
java-shib-attributeandjava-shib-metadata, down to 28M and 17M from 85M each.Anachronistic history largely achieved.
Java 19 is now GA. Mostly feature previews: record patterns, virtual threads, structured concurrency.
It is now confirmed by Oracle that Java 21 (September 2023) will be the next LTS release.
Note that this is only two years after Java 17, not the three-year gap between 11 and 17 they initially claimed would be the pattern going forward.
One interesting question is whether virtual threads make it into Java 21. Probably largely a concern for the containers (Jetty 10/11 already has some support), but we will want to be compatible.
I think we more or less have to say we’ll support Java 21 for IdP v5, and that would mean adding it to the Java 17 platform description. We don’t have to make that promise now, but I don’t think it’s in doubt.
I think we probably want to say the same for IdP v4, unless v4 is already unsupported by next September (which seems unlikely). Again, we don’t have to say this now.
The rule of thumb looks like it will end up being that we support the most recent LTS at the time of a major release, and two subsequent ones. (11, 17, 21 for v4; 17, 21, 25 for v5).
In passing: Debian 11 “buster” shipped with a Java 17 EA release only, but now has an up-to-date 17.0.4. I’ve updated the Java Distributions page to add that to the “partially supported” category.
I’m now aiming to make an MDA 0.10 release by early 2023, as UKf and InCommon appear able to adopt around then.
This will now target the same stack as IdP v5: Java 17, Spring Framework 6 (and
java-shib-shared).
I’ve started thinking about getting more formal about the Java 17 platform, specifically supported distributions.
Proposal for a new section in Java Distributions:
Corretto 17 for Linux as primary distribution.
Fully supported: Corretto 17 for Linux, Corretto 17 for Windows, RH OpenJDK 17 as shipped in RHEL/Rocky 8, RH OpenJDK 17 as shipped in RHEL/Rocky 9.
We don’t yet know what Amazon and Red Hat are going to do about Java 21, so we can’t add that yet.
Partial support: Debian’s OpenJDK 17 on Debian 11 “buster”.
Spring Framework 6 is nearly here:
6.0.0-RC1 on 2022-10-12 (next week)
6.0.0-RC2 on 2022-10-20 (Spring Boot 3.0.0-RC1 on this date too).
