@svenruppert In #JabRef, we stick with #JDK21, because the new features of JDK22 do not outweigh the updates the effort of Linux distributions packaging our app with a more recent #JDK. Regarding #JavaFX, we always go with the latest release - and also build with the latest EA version to enable testing by Linux users whether their bugs (mostly with Gnome and i3) are fixed. Our #GitHub #workflow is https://github.com/JabRef/jabref/blob/main/.github/workflows/deployment-jdk-ea.yml.

Dive into the latest advancements in #Java with our latest article on JDK 21's virtual threads: https://bit.ly/4cEppIA

This analysis compares the performance of virtual threads with Open Liberty's thread pool, focusing on key findings such as throughput, ramp-up times, and memory footprint. While virtual threads offer several advantages, they also show unexpected performance issues, especially in CPU-intensive workloads.

This analysis guides Java developers on when and how to use virtual threads in their applications.

avis partagé !! RT @AlexisHassler Avec le JDK 21, les virtual threads sont séduisants. Par contre au niveau inspection c'est galère. #jdk #jdk21 #VirtualThreads

Il n'apparaissent pas avec jstack, jconsole ou visualvm.
Avec jcmd, on les voit avec la commande Thread.dump_to_file, mais pas avec Thread.print 🤯.

12 Lessons Learned From Doing The One Billion Row Challenge:
https://foojay.io/today/12-lessons-learned-from-doing-the-one-billion-row-challenge/

:java: #java #1BRC #jvm #jdk21

There has been some interesting discussion on #JakartaEE 11 and #Java servers over on Twitter. The draft of the spec has been updated to require JDK 17 rather than requiring JDK 21. I agree with the decision. To maximize adoption, JakartaEE must support JDK 17 and optionally JDK 21. Dropping JDK 11 is the best we can hope for right now.

My CalculateAverage code has been executed for the :java: #1brc challenge.
I didn't get the expected result on the advertised "This CPU will impress you with its multi-tasking performance." CPU (See graph).
Also did some jdk8 tests.

I've created an open-source :java: Java library to make code using virtual-threads easier to write and to read.

It's already in Maven repository.
