Vaadin Java 21 (Runtime / Compile Time) Ready?

[knoobie]

Describe your motivation

Looking at https://github.com/vaadin/platform/releases/tag/24.3.0 - it only mentions Java 17 as "Supported technologies", but also Gradle Requirement was increased so that 21 is fully supported.. so.. is Vaadin 24.3 fully ready?

Describe the solution you'd like

Vaadin supports Java 17,21,22+

Describe alternatives you've considered

Java 21 is supported. I guess we need to adjust how we present this in the release notes.

The reason we're not doing something like "Java 17 or newer" like we do for various other things is that we wouldn't want to keep promising eternal support for the non-LTS versions like 18. On the other hand, this might also be the case for other technologies.

You could do it like other frameworks do, e.g. "17 or 21+" and update that if necessary - for example Hibernate: https://hibernate.org/orm/releases/6.4/
