      Workflow Plugins 1.2

    Description

      Steps to Reproduce:
      1) Create a new workflow job that pulls from git and is set to poll scm infrequently (as appropriate for using scm hooks).
      2) Run the job once manually.
      3) Trigger an scm poll by invoking jenkins-url/git/notifyCommit with appropriate query string.

      Result: Status 200 & Body of response states that polling of the test job was scheduled.

      4) Restart Jenkins (sudo service jenkins restart or similar)
      5) After Jenkins returns to normal running status repeat step 3.

      Result: Status 500 and the stack trace appended to the end of this report.

      6) Run the job again manually (step 2).
      7) Repeat Step 3.

      Result: Status 200 & Body of response states that polling of the test job was scheduled.

      In summary, scm triggers fail post-jenkins restart for workflow jobs until each such job is run once. I did not thuroughly test with multiple jobs but I believe it is the case that every workflow job must be run manually before any job (even non-workflow) can be triggered.
