Fix build on Apache s390x Jenkins slave

[uschindler]

Description

See https://issues.apache.org/jira/browse/LCN4C-9:

Apache Lucene CI is disabled for s390x recently on 29th Feb. Couldn't find any specific reasons why it's disabled.

https://ci-builds.apache.org/job/Lucene/job/Lucene-Check-main%20(s390x%20big%20endian)/

Can you please check and let us know if anything is needed.

Version and environment details

No response

We need Java 21 now, which may not be installed on that machine, so I disabled it while switching Jenkins jobs- I can quickly fix thus. If you tell me which Java 21 setup we can use for Apache Lucene main tests, I can reenable the job. Is selecting "Latest Java 21" working on that slave node?

Sorry for not making progress here, I just quickly disabled it to setup jobs. Will try in a moment.

Quick feedback: Yes it does not work with Java 21:

[Lucene-Check-main (s390x big endian)] $ "/home/jenkins/jenkins-home/712657a4/workspace/Lucene/Lucene-Check-main (s390x big endian)/gradlew" -Dtests.haltonfailure=false -Dtests.badapples=false --continue check

ERROR: JAVA_HOME is set to an invalid directory: /home/jenkins/tools/java/latest21

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

@uschindler I have created an issue to install Java 21 on s390x nodes
https://issues.apache.org/jira/browse/INFRA-25589

[uschindler]

I disabled both failing jobs until the INFRA ticket is resolved. Please ping me if you have updates.

Apache Lucene builds are passing now.
https://ci-builds.apache.org/job/Lucene/job/Lucene-Check-main%20(s390x%20big%20endian)/

https://issues.apache.org/jira/browse/INFRA-25589 is still open for installing Openjdk 21 or hotspot

Thanks all fine.

It would be nice to get a feedback by Infra. I am tempted to install a fake job to just print version information.
