Baptiste Mathus added a comment - 2018-11-29 22:14 markewaite I strongly suspect this one is actually: a duplicate of JENKINS-52017 (which should IMO be reopened, but I'm interested about what you think before I proceed) an issue on the metrics-plugin component instead of core caused by https://github.com/jenkinsci/metrics-plugin/blob/d9b0eb3c576dd1aeff3bff113ca9cd0253aef40f/src/main/java/jenkins/metrics/impl/VMMetricProviderImpl.java#L226 FTR, I arrived here after googling and searching an existing for something I've seen already with Evergreen Java 11 flavor, and just now in a local test: nov. 29, 2018 10:59:35 PM hudson.ExtensionFinder$GuiceFinder$FaultTolerantScope$1 errorWARNING: Failed to instantiate Key[type=jenkins.metrics.impl.VMMetricProviderImpl, annotation=[none]];

Mark Waite added a comment - 2018-11-30 12:30 It makes sense to me to close this report as a duplicate of JENKINS-52017 and fix it there. The setAccessible call that you identified certainly seems like the issue to me.
