After upgrade Jenkins to 2.116 I see in the logs the following error:
Apr 11, 2018 9:06:15 PM WARNING org.jenkinsci.remoting.util.AnonymousClassWarnings warn
Attempt to (de-)serialize anonymous class javaposse.jobdsl.plugin.LookupStrategy$2 in file:/var/lib/jenkins/plugins/job-dsl/WEB-INF/lib/classes.jar; see: https://jenkins.io/redirect/serialization-of-anonymous-classes/
It is not related to the plugin version - I tried to downgrade to 1.67 - problem still exists in this version. Before Jenkins upgrade (it was a direct upgrade from 2.114 to 2.116) I hadn't had such errors.
