Here is the impl of Set.copyOf:

     static <E> Set<E> copyOf(Collection<? extends E> coll) {
         if (coll instanceof ImmutableCollections.AbstractImmutableSet) {
             return (Set<E>)coll;
         } else {
             return (Set<E>)Set.of(new HashSet<>(coll).toArray());

Best regards,
