    Description

      When running a simple, the Jenkins logs show the following WARNINGS:

      How to Reproduce

      • Create a simple job that does nothing
      • Create a simple MultiJob project with one phase, which contains the reference to the job, see multijob-config.png
      • Build the MultiJob

      You will see the stacktrace appearing several times (3 times), see logs-after-build.log

      Impact

      This is critical as when many jobs run at the same time, it is polluting at such extent that it slow down the Jenkins server and make it unresponsive.
