Sam Van Oort added a comment - 2018-06-18 17:13 - edited Workaround, per this blog: https://blog.codefx.org/java/five-command-line-options-to-hack-the-java-9-module-system/#Accessing-Internal-APIs-With--add-exports Add the following to the Java options: --add-opens jdk.management/com.sun.management.internal=ALL-UNNAMED We could probably make this more specific to just the classes needed, of course (and just the plugin module once it has one).

Stephen Connolly added a comment - 2018-06-21 12:23 was this resolved by JENKINS-52061 ?

Baptiste Mathus added a comment - 2018-11-29 22:11 - edited Pretty sure this is actually unresolved, caused by https://github.com/jenkinsci/metrics-plugin/blob/d9b0eb3c576dd1aeff3bff113ca9cd0253aef40f/src/main/java/jenkins/metrics/impl/VMMetricProviderImpl.java#L226 . Will double-check and possibly reopen soonish I confirm that it does not stop Jenkins from starting though.
