Hi Stuart,
I hope you had a save travel home from Antwerp.
We talked at Devoxx Antwerp about a flaw with the programmatic accesibility of jimage in JDK21.

only relevant to #scala people (if they exist). i’ve been using cats-effect ecosystem + the cps async plugin but ox seems better in every conceivable way for more direct style. is this too good to be true? aside from the obvious restriction of being JDK21+ only.

FYI to all, the ORDS team just published a new patch, 25.1.1. Now available for download here: www.oracle.com/database/sql...
Two small bug fixes, and an update to our Jetty library. Happy Friday 😍

Mas é exatamente isso, só as vthreads foram "finalizadas" menos de 2 anos atrás, então é difícil competir na versão que eles eram na JDK21. Mas bota pra rodar em cima de uma JDK25 early-access pra você ver, kkk. Só uma coisa que não vai ser resolvida, que é pipelining que não dá pra fazer.

Ah, e pra ser explícito, a melhoria do polling na JDK22 usando vthreads e etc pode ser olhado nesse JBS e relacionados: bugs.openjdk.org/browse/JDK-8...
Não perca fé nas vthreads @hugomarques.dev o que era bom na JDK21 vem com tudo desde então, na JDK25 então, game changer (de novo).

Not an official #javachampion, but I if you want my opinion, that seems to be a legacy library. Many companies are already working with the JDK21 and that is not even the latest one. If it compiles with Java 8, and not with any of the above then that is significant.

Where is it spec'd that MethodHandle instances are reliably interned? Simple tests like:
```
assertSame(
MethodHandles.constant(Object.class, "hello"),
MethodHandles.constant(Object.class, "hello"));
```
fail (JUnit4, jdk21).

For class instances that are enforcibly interned, such as Class, MethodHandle, etc. This may just be your "certain low level classes" bucket, but it is possible to write classes in a way that instances that are .equals() but not == cannot exist.

So I spent more than a month struggling with migrating a project from jdk7 to jdk21 ... only to know that I can integrate Github Copilot into my intellij IDE during @edburns.bsky.social session at #javaland 😬😬

Na JDK21 já tinha, mas como preview (JEP 443). Se botar --enable-preview tá pra jogo, pq foi pra 22 sem mudanças, então é o mesmo da preview. "We here propose to finalize this feature without change."

The GitHub repo now has GitHub actions running each example. You can see the output without installing any software! Just find the "Run scripts with Gradle" step in the execute job for the technology you're interested in. E.g. ArcadeDB running on GraalVM JDK21:
github.com/paulk-asert/...
#groovylang
github.com/paulk-asert/...

Random Ask, does anyone know if it's possible to do this using `nix-commands`? IE `nix shell nixpkgs#jdk21`?

I love Nix because replace `#!/bin/bash` at the start of a shell script with
#!/usr/bin/env nix-shell
#! nix-shell -i bash
#! nix-shell -p bash jdk21
And now that script has guaranteed dependencies met. And you can use any interpreter you want, be it bash, python, or whatever.
