Completed pruning of java-shib-attribute and java-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.
Oracle are now indicating 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.
- They have talked about this changed cadence before in the “future hopeful” so this is not a complete surprise. I expect this to be confirmed at JavaOne, which is October 17–20.
- The interesting question is whether things like virtual threads make it into Java 21. Probably largely a concern for the containers, but we will want to be compatible.
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).
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).
