      After restarting jenkins, EC2 nodes fail to start with the following stacktrace:

      ERROR: Unexpected error in launching an agent. This is probably a bug in Jenkins

      If we go to /configure and just save the current configuration, the nodes will successfully start after that. Since we have many nodes, this workaround is quite impractical.

      Same problem but different stacktrace: https://issues.jenkins-ci.org/browse/JENKINS-55473
