We need later move to Java 11 and migrate some code to VarHandle I think, as Java 25 is coming next year, which is a LTS version.

pjfanning · 2024-11-29T07:50:36Z

The biggest issue is having our builds fail if we use any deprecated code. Scala 2.13.15 upgrade is blocked for similar reasons.

He-Pin · 2024-11-29T08:47:47Z

How about add @nowarn("msg=deprecated") on these classes? @pjfanning , I have not setup my new mac, will try when back home.

pjfanning · 2024-11-29T08:50:36Z

We have to support 3 Scala versions and the deprecation warnings are different on them. Add extra nowarn annotations and they can fix one build but break another.

He-Pin · 2025-01-17T19:43:19Z

I'm working on this, I think we should test the latest JDK too.

He-Pin · 2025-01-20T12:44:12Z

@pjfanning 3.3.5-RC3 is released.

He-Pin · 2025-02-15T07:27:28Z

@pjfanning how about update this pr to make it test JDK23, it should be ok now.

He-Pin · 2025-03-20T02:59:26Z

We can now test with JDK 24.

He-Pin · 2025-03-21T04:06:30Z

@SethTisue Is there any update for next 2.12.x for JDK 24?

mkurz · 2025-03-21T11:16:13Z

@SethTisue If you cut a new Scala 2.12.x release, it would be great if that would also already unlock Java 25 by upgrading asm (I hope they cut a new release soon) - so we can test early with latest ea builds already (since it's the next LTS) :

pjfanning · 2025-03-21T11:30:29Z

Scala 2.13.16 run went ok - some test failures due to TLS changes in Java 24. Some TLS protocols or cipher suites have been removed.

Scala 3.3.5 run failed with:

@mkurz @He-Pin you can state your case over at https://contributors.scala-lang.org/t/scala-2-12-21-release-planning/6753

He-Pin · 2025-05-09T12:41:24Z

@pjfanning @raboof Wdyt about it, should we run a nightly test with JDK24?

raboof · 2025-05-09T13:32:43Z

Wdyt about it, should we run a nightly test with JDK24?

Are the failures in this branch now resolved? If so might be nice (though perhaps we should move some of those to weekly rather than nightly?)

pjfanning · 2025-06-07T10:11:46Z

we also hit issues with TLS ciphers that are no longer supported
