JHipster 8 doesn't work with Java 22

[mraible]

Overview of the issue

JHipster 8 doesn't work with Java 22. If you're using Gradle, you get an error:

BUG! exception in phase 'semantic analysis' in source unit 'precompiled_…' Unsupported class file major version 66

If you're using Maven, CRLFLogConverterTest doesn't pass.

Motivation for or Use Case

We should support the latest release of Java.

Reproduce the error

sdk install java open-22
jhipster --defaults

Suggest a Fix

Upgrade to Gradle 8.7 and fix the test.

JHipster Version(s)

8.2.0

Do we have already update to spring boot 3.2.4? The class file error comes from the gradle boot plugin which need to be updated to 3.2.4 for java 22 as far as I can tell.

EDIT: nevermind, it should be 3.2.4 already 🤔

v8.2.1 was released with spring-boot 3.2.3.
Tests results should be updated.

On master we have 3.2.4 right? At least thats what I see in a generated application. Didn't check yet if that version is really used eventually.

Seems like jhipster's reactive stack will have to wait until byte-buddy && BlockHound are resolved...
