Expected behavior of a Streams.cycled() instance - found issues and questions

[Peter Levart]

Hi,

I wonder if the Streams.cycle(emptyStream) should return an empty stream 
instead of:

     public static<T> Stream<T> cycle(final Iterable<T> source) {
         Objects.requireNonNull(source);

         // Check if the source is empty
         if (!source.iterator().hasNext()) {
             throw new IllegalArgumentException("Source Iterable to 
cycle elements from must not be empty");
         }


Regards, Peter
