Description:

It seems as though jenkins somehow gets in a situation where at the end of running a job, at the point of trying to publish nunit results it throws an NPE, of the form:
ERROR: Publisher hudson.plugins.nunit.NUnitPublisher aborted due to exception
java.lang.NullPointerException

Once this starts happening it continues to happen for every build for that particular job. A restart does not stop this behaviour from happening. We noted a while back that deleting the build history from the filesystem for this job does allow it carry on successfully, until such time as the error appears again.
Very recently a team member noted that the number of builds in the history for that job was equal to (or thereabouts
[most recent #405 oldest #306
) to the value stored in the configuration setting 'Max # of builds to keep' (in our case 100). This could be a co-incidence, and I've upped the setting to 200 to see if builds start working again (but this takes ~6 hours to reach the failing job), but it does look like a smoking gun :)
I had hoped that it would be related to [https://issues.jenkins-ci.org/browse/JENKINS-16194] but having upgraded to the latest version we still see this issue.
I'm mostly logging this in case others are seeing it ;)
