Jenkins LTS will drop support for Java 11 in October

https://www.jenkins.io/blog/2024/06/11/require-java-17/

The first LTS release to require Java 17 or newer will ship at the end of October 2024.

After #3030 most of our agents are being run with Java 17.

Scanning through https://ci.nodejs.org/computer/ it looks like Java 11 is still being used on:

• CentOS 7
• Debian 10
• FreeBSD 12
• SmartOS
• IBM i

We can drop the CentOS 7 machine.

@abmusse Is Java 17 available on IBM i?

[abmusse]

@richardlau

Yes, Java 17 is available but it looks like its not packaged as an RPM.
I'm investigating what would be required to upgrade to Java 17.

[richardlau]

@nodejs/build-infra Do we want to keep Debian 10 around in the CI or just remove? It's End-of-Life as of June 2024.

(If we want to keep it, there are options for Java 17 -- both Oracle and Adoptium offer Java 17 that should work on Debian 10 AFAICT.)

[sxa]

Debian 10 has the same glibc level as RHEL8 so it's technically feasible to keep that going as a functional system ....
However since it's out of support I'm not sure I'd want to keep it on the network, so perhaps we should just upgrade it to a later release.

[richardlau]

Another reason to remove Debian 10 is that npm 10.8.3 contains an update to node-gyp that now requires Python 3.8. The packaged version of Python on Debian 10 is 3.7.3. While it might be possible to install newer Python 3 on the machine by other means, that in combination with the Java 11 issue will add more maintenance overhead to keeping this End-of-Life platform active in the CI.

Removal of Debian 10 will still leave Debian 11 and 12 in the CI, so we'll still have coverage on Debian there.

On the release CI, I see only release-osuosl-centos7-arm64-1. Can we remove that builder? I see nothing in its build history.

Yes, we don't use CentOS 7 anymore (from Node.js 18 onwards).

FreeBSD is done.

IBM i update: plan is for the machines to be updated to IBM i 7.4 next week. After that we (@abmusse ?) will need to update Jenkins and Ansible.

[abmusse]

Yes Once the machines get updated to 7.4 we will need to do some config changes to pickup Java 17.

[abmusse]

We now have Java 17 installed on the IBM i CI machines 🎉

[targos]

CentOS 7 and Debian 10 machines were removed.
The remaining ones with Java 11 are all SmartOS:
