    Description

      I have several projects on my Jenkins server.
      My projects stored in Mercurial SCM.
      For trigger build I use notifyCommit as mentioned in plugin WiKi:

      http://localhost:8080/mercurial/notifyCommit?url=<repository remote url>
      

      Most of my projects builds after trigger, but one project when get notification send me error report (see attached file jenkins-response.html).

            First of all bad objects must not to be send to queue, object/Runner has no sense when job is null, so nothing can be changed in hashCode, because scm plugins usually send it through SequentialExecutionQueue to exclude duplicated runs for the same job.

            Added annotations, stubs and tests in https://github.com/jenkinsci/jenkins/pull/1783
