🗳️ Grails 7 Scope - What should the Java Baseline for Grails 7 be?

[sdelamo]

Since Spring Boot 3.0, the baseline version is Java 17. As we plan to support the latest spring boot, I think we need to raise to a minimum of Java 17. Maybe we could take the opportunity to go to 21 as the Java baseline.

What would we gain from raising the baseline from 17 to 21?
(You can already run Grails 6 on Java 22)

Enabling virtual threads is to my understanding just a Spring Boot setting if you are running the app with Java 21+.
spring.threads.virtual.enabled=true

I think we should follow the baseline of the Spring Boot version used.
Spring Boot 3.3 is baselined on Java 17.

(https://github.com/grails/grails-core/tree/7.0.x is already on Java 17)

I would follow Spring Boot dependencies versions as well, adding Gradle to the list of matching versions.

We are going in the 17 as Java baseline direction.
