build support: java 24

[rmuir]

Description

java 23 has disappeared and has been replaced with java 24.

the build currently requires 23 exactly, which creates a hurdle for users, since it is difficult to get: does not exist in operating system package manager, must be dug out of a graveyard, etc.

yes, i know the problem of gradle here, but that doesn't excuse their behavior. they shouldnt be parsing classfiles of the jvm anyway.

This is terrible. I'll take a look.

I tried allowing 24 and gradle only failed in the usual way (incompatible classfile): we have to wait for them to issue a gradle release that "supports 24" so they can parse the classfiles of the jdk :(

gradle/gradle#32290

They do tons of weird stuff these days that require bytecode manipulation and touching everything upon loading. I don't think there is a way around other than wait for that issue to be solved. I'll keep an eye on it.

maybe this one will fix it long-term and this is the last time we have to go thru it? unfortunately it just went live in java 24 so it doesn't help us now: https://openjdk.org/jeps/484

Really nice indeed! Sadly, I think it'll take just about a million years before it propagates through all the layers until it can hit gradle (but I'd love to be proven wrong). ;)

Argh! sorry, I caused this issue by upgrading to JDK 23. Maybe that was a mistake, for this reason (a non-LTS can disappear before the tools catch up with the newly released major JDK).
