EmptyStackException from CpsFlowExecution.onProgramEnd

Issue Type:	Bug
Assignee:	Unassigned
Components:	workflow-cps-plugin
Created:	2020-04-21 18:01
Priority:	Minor
Reporter:	Jesse Glick

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?
