[JENKINS-39044] NPE thrown when firing upstream jobs #17611
Description
I've run into an issue where, when trying to trigger a pipeline job from a freestyle (classic), I'm seeing a NPE in the jenkins log. This happens when the pipeline job is an upstream of a freestyle job; and trying to watch for new builds of the freestyle.
The full stack trace is:
WARNING: RunListener failed java.lang.NullPointerException at hudson.model.Result.isBetterOrEqualTo(Result.java:130) at jenkins.triggers.ReverseBuildTrigger.shouldTrigger(ReverseBuildTrigger.java:139) at jenkins.triggers.ReverseBuildTrigger.access$000(ReverseBuildTrigger.java:89) at jenkins.triggers.ReverseBuildTrigger$RunListenerImpl.onCompleted(ReverseBuildTrigger.java:258) at hudson.model.listeners.RunListener.fireCompleted(RunListener.java:214) at hudson.model.Run.execute(Run.java:1765) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:401)
This is preventing the upstream job from getting triggered.

Jenkins API explicitly prohibits passing null: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/model/Result.java#L129-L131. Hence there is a bug in the core

On the other hand, https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/jenkins/triggers/ReverseBuildTrigger.java#L139 assumes that threshold is somehow not specified in your job
Please provide your job configuration. Do you also use any Job Generators to create such config?

The attached files sample-classic.xml
and sample-pipeline.xml
cause the N.P.E. I do not have generators, I created these by hand.
Add reverse trigger NPE detection attempt
