    • CloudBees Core 2.222.2.1-rolling (I think)

      No idea how to reproduce; saw this after startup about a possibly stuck/broken build:

      ... WARNING org.jenkinsci.plugins.workflow.cps.CpsVmExecutorService reportProblem

      Not entirely obvious what the most graceful response is here. Call createPlaceholderNodes?
