    Description

      If we (by mistake) swap arguments of HOP window, we end-up with invalid WindowFn, that can produce empty windows, which then subsequently results in
      java.lang.IllegalArgumentException: WindowedValue requires windows, but there were none

      We need to verify that the arguments are correct prior to constructing the WindowFn.
