      You do not learn anything new using that option. The stack trace is now:

      2017-03-20 18:10:27,198: [DefaultQuartzScheduler_Worker-10] ERROR GrouperLoaderType.syncGroupList(1422) - - Error on group: mystem:mycourse:instructors_systemOfRecord java.lang.RuntimeException: Problem deleting groups for name: mystem:mycourse:instructors_systemOfRecord, though did delete 0 groups

      ... 6 more

      The error is thrown every hour when the loader job runs (many other sub jobs
      for that loader job run successfully, but this subjob is throwing the NPE
      consistently).

      Thanks,
