hello!
i have recently upgraded jenkins from version 2.462.3 to 2.516.2 and have ran into an issue with jenkins being seemingly unable to write certain configuration options to the local storage. the relevant stacktrace is a the bottom of this post. what i have tried:
- all plugins are disabled
- removing all the jenkins config files and forcing jenkins to recreate them
this upgrade required moving to Java 17 (17.0.2 openjdk) and upgrading tomcat to version 10. i am also using httpd and tanuki wrapper version 3.6.3. some of the configuration options appear to have been written such as the LDAP security config and the system message, but other things like the environment variables and the built-in node config dont persist. this causes all of the config to be dropped on a restart of the jenkins service.
Jenkins setup:
Jenkins: 2.516.2
OS: Linux - 3.10.0-1160.138.1.el7.x86_64
Java: 17.0.2 - Red Hat, Inc. (OpenJDK 64-Bit Server VM)
