It looks like after updating to the latest Jenkins LTS (https://www.jenkins.io/security/advisory/2022-09-09/) several agents are failing to connect to the server.
e.g. example failure from one of the agent logs:
WARNING: LinkageError while performing UserRequest:hudson.slaves.SlaveComputer$SlaveVersion@435cd082
java.lang.UnsupportedClassVersionError: Failed to load hudson.slaves.SlaveComputer$SlaveVersion
...
Caused by: java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=hudson/slaves/SlaveComputer$SlaveVersion, offset=6
...

INFO: Terminated
Looks like now that Jenkins has dropped support for Java 8 (#2984) the agents also require Java 11+.
