damccorm opened a new issue, #20999: URL: https://github.com/apache/beam/issues/20999
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.
