    When a build job is changed to use a new build node, and also the previously used node is removed from the Jenkins setup, then SCM polling starts to fail with: {noformat} ERROR: Failed to record SCM polling for hudson.model.FreeStyleProject@587918[jobName] java.lang.NullPointerException at hudson.plugins.zentimestamp.ZenTimestampEnvironmentContributor.buildEnvironmentFor( at hudson.model.Run.getEnvironment( at hudson.model.AbstractBuild.getEnvironment( at hudson.scm.SubversionSCM.compareRemoteRevisionWith( at hudson.scm.SCM._compareRemoteRevisionWith( at hudson.scm.SCM.poll( at hudson.model.AbstractProject._poll( at hudson.model.AbstractProject.poll( at hudson.triggers.SCMTrigger$Runner.runPolling( at hudson.triggers.SCMTrigger$ at hudson.util.SequentialExecutionQueue$ at java.util.concurrent.Executors$ at java.util.concurrent.FutureTask$Sync.innerRun( at at java.util.concurrent.ThreadPoolExecutor$Worker.runTask( at java.util.concurrent.ThreadPoolExecutor$ at {noformat} This is because AbstractBuild#getBuiltOn may return null, but this case is not handled in hudson.plugins.zentimestamp.ZenTimestampEnvironmentContributor#buildEnvironmentFor.
