      After upgrading to latest 1.501 (from 1.484) I see this error a lot in my Jenkins log surging from several actions: scm polling, columns sort, dashboard views, etc.

      I've disabled Downstream+buildview+plugin because of this error some jobs wouldn't even load, while other plugins like DashboardView would get dogslow while still throwing this same stacktrace, but still the same stack trace keeps showing up even in the most basic things like SCM Polling.

      Please check.
