We cannot currently upgrade Jenkins from 2.517 to 2.518.

Our Windows Server 2016 running on java 21.0.7 2025-04-15 LTS are failing the node registration with the following error: 

  - io.jenkins.cli.shaded.org.apache.sshd.common.SshException: [ssh-connection]: Failed (NoSuchProviderException) to execute: JCE cannot authenticate the provider BC

  - Caused by: java.util.jar.JarException: The JCE Provider file jenkins-cli.jar is not signed

We noticed the following change made on 2.518 that seems to be related: https://github.com/jenkinsci/jenkins/pull/10788
