Official supported Java version?

[philippart-s]

Hi,

Is there a documentation where I can find the official supported Java version?
I find this blog post for Java 17: https://quarkus.io/blog/java-17/
When I check the quarkus CLI I found this for Java 17 & Java 21:

quarkus create app --help

Create a Quarkus application project.

Usage: quarkus create app [-Beh] [--dry-run] [--refresh] [--[no-]
                          registry-client] [--verbose] [--config=CONFIG]
                          [--description=DESCRIPTION] [--name=NAME]
...

Options:
  -B, --batch-mode           Run in non-interactive (batch) mode.
...

Quarkus version:
...

Build tool (Maven):
...

Target language:
      --java=<javaVersion>   Target Java version.
                               Valid values: 17, 21
                               Default: <<detect java runtime version>>
...

When I use Java 24 I've got some warnings at startup:

quarkus dev
WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::load has been called by org.fusesource.jansi.internal.JansiLoader in an unnamed module (file:/Users/sphilipp/.m2/wrapper/dists/apache-maven-3.9.9-bin/33b4b2b4/apache-maven-3.9.9/lib/jansi-2.4.1.jar)

WARNING: Please consider reporting this to the maintainers of class com.google.common.util.concurrent.AbstractFuture$UnsafeAtomicHelper

So I'm wonder if Quarkus supports Java 24.

I'm using Picocli and saw this issues: #48882 & #47769

And finally it's the reason why I want to know the "official" position 😉

From what I can see the two warnings are related to Maven. And we launch Maven from the CLI by running your typical Maven command line.

You don't have the warnings when running plain Maven?

[philippart-s]

Yes you are right: https://issues.apache.org/jira/browse/MNG-8760, issues concerning Picocli have caused me errors.
So I deduce that there is no official max version? (only the minimal version on 17)

We officially support Java LTS releases but we will fix whatever is in the way of more recent versions.
And the Mandrel team is constantly testing the current GraalVM dev version.

Now that we have solved our CI bandwidth issue, we should probably run our usual CI tests also with the latest.
