Could we use JDK 25 in Docker images?

[Ostrzyciel]

Currently in Docker images of RDF4J, JDK 17 is used:

rdf4j/docker/Dockerfile-tomcat

Line 14 in f92d108

FROM tomcat:9-jre17-temurin-jammy

JDK 25 introduces a lot of performance improvements, especially since JDK 17/21. In our internal workloads RDF4J works completely fine on JDK 25.

See Oracle's talk from a month ago: https://www.youtube.com/watch?v=223_7r0H6OE&t=125s

Could we change the Docker images to ship with the latest LTS JDK?

I think it should be fine. I'm also running java 25 locally and only issues I've seen are with some tests.

For 5.3.0 the Java runtime has been updated in the docker containers.

In 6.0 we now support newer versions of application servers (Jetty 12, Tomcat 10) after the migration to Jakarta (see #3559)

For reference: I have created a dedicated follow up for updating application servers as part of 6.0 ib #5801 and with that propose to close this task
