I reversed this change :

-final Collection<? extends E> c;
+        final Collection<E> c;

in Collections.UnmodifiableCollection instead opting or casts in the forEach and spliterator Methods.

- I wonder if it's worth it to have the NONNULL characteristic change in Collections::singletonSpliterator depending on element. 


- needs an overridden spliterator providing ORDERED for it's entry set. (I can do this tomorrow if needed).


- I am surprised the spliterator is not ORDERED.
