Hi all, I have recently upgraded my dogtag's foundation to Fedora 41 and then found I had to do some maintenance work. The system is up to date: [root@ca2 ~]# pki-server --version PKI Server Command-Line Interface 11.6.0-1 [root@ca2 ~]# pki-server status <censored> Instance ID: <censored> Active: True Nuxwdog Enabled: False Unsecure Port: 8080 Secure Port: 8443 Tomcat Port: 8005 CA Subsystem: SD Manager: True SD Name: IT-Service Lehmann <censored> SD Registration URL: https://<xensored>.de:8443 Enabled: True <snip more details> The result trying my maintenance task was the following: # LANG=C pki-server ca-user-cert-find caadmin -i <censored> Error: LinkageError occurred while loading main class org.dogtagpki.server.cli.PKIServerCLI java.lang.UnsupportedClassVersionError: org/dogtagpki/server/cli/PKIServerCLI has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0 So I checked, found that the dogtag dev guide indicates that openjdk-17 should be a good choice. However, I found that I seem to use a current Java environment by default: [root@ca2 ~]# java --version openjdk 21.0.7 2025-04-15 OpenJDK Runtime Environment (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6) OpenJDK 64-Bit Server VM (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6, mixed mode, sharing) I also found that I have older versions installed still -- OpenJDK 11 and 1.8. I removed those using dnf, verified I use JDK17 by default with 'alternatives java', retried the pki-server program, and -- [root@ca2 ~]# LANG=C pki-server ca-user-cert-find caadmin -i <censored> runuser: failed to execute /usr/lib/jvm/jre-11-openjdk/bin/java: No such file or directory Looks like there's a particular ja aversion or path hardcoded somewhere, and after several generations of updates of this system, some inconsistency developed. The result being I can't play with my CA anymore. Any advice so I can continue playing, learning, and actually using my CA instance?
