Hello, I noticed that Apache Solr CI support for the s390x architecture has been disabled recently. We rely on Apache Solr on s390x systems, and the removal of CI coverage makes it more difficult to ensure ongoing compatibility and catch regressions early. I've raised a JIRA issue about this concern (https://issues.apache.org/jira/browse/SOLR-17807), and I was advised there to ask on the solr-dev mailing list for more information. We're happy to help if there's an opportunity to collaborate on restoring support for s390x. Thanks in advance for your time and help.
Regards, Sudip Roy
