ClassCastException: FreeStyleBuild cannot be cast to WorkflowRun on getCommitters

      I just installed Build Monitor view plugin and configured a view. I get a HTTP 500 and an empty view with the Jenkins error window.

      Server logs are below. It is repeated and there are some more errors, but I think they are just follow-on errors.

      It seems to have to do with getCommitters. 

      1. We have both freestyle and pipeline jobs in the view.
      2. Interesting is that sometimes the view loads OK.
      3. After configuring view to not show committers it works consistently.
