Hi,
I am running Jenkins 2.63 on an Ubuntu 14.04 machine and after each successful
pipeline build I get a null pointer in the RunListener:
May 30, 2017 9:10:49 AM WARNING hudson.model.listeners.RunListener report

For none pipeline builds I get the error without a stack trace.
The problem is that downstream jobs do not trigger.
During start-up there was an error loading an additional component, I am not
sure if this is related:
May 30, 2017 9:10:25 AM INFO
hudson.ExtensionFinder$GuiceFinder$FaultTolerantScope$1 error
Failed to instantiate optional component
hudson.plugins.build_timeout.operations.AbortAndRestartOperation$DescriptorImpl;
skipping
Another error I see quite frequently in the logs is (skipping the stacktrace
because it is huge):
May 30, 2017 9:21:03 AM WARNING
org.jenkinsci.plugins.workflow.cps.CpsFlowExecution getCurrentHeads
null
java.lang.IllegalStateException: List of flow heads unset for
CpsFlowExecution[null]
Given that I have not found any other reports of the problem I think it is
related to some installed plugin or combination of installed plugins. Is there
a better way to find out which plugin causes trouble better than removing them
one by one?
Regards,
Lukas
