def <=>(oth)
  # Note that prior to ruby 2.3.0, if a <=> method threw an exception, ruby
  # would silently rescue the exception and return nil from <=> (which causes
  # the derived == comparison to return false). Starting in ruby 2.3.0, this
  # behavior changed and the exception is actually thrown. Some comments at:
  # https://bugs.ruby-lang.org/issues/7688
  #
  # So simply return nil here if any of the needed fields are not available,
  # since attempting to access a missing field is one way to force an exception.
  # This doesn't help if the  <=> use below throws an exception, but it
  # handles the most typical cause.
  return nil if !oth.respond_to?(:priority) ||
