      I'm seeing the following exception in my jenkins log:

      I have been able to reproduce this by creating a new job in the disabled state. Waiting for a normal execution period to pass, then re-enabling the job. Each time the trigger fails until I re-save the project, then appears to trigger properly.

      My project config is the following:
