is this test code correct?
{code:java}
// public static void main(String[] args) {
 Set<String> strings = new HashSet<>();
 strings.add("this is testtstring"); 
 Iterator<String> iterator = strings.iterator();
 List<String> out = IteratorUtils.toList(iterator);
 Iterator<String> stringIterator = out.iterator();
 while(stringIterator.hasNext()){
 System.out.println(stringIterator.next()); 
} }

{code}
it seems to be working

> org.apache.commons.collections.IteratorUtils.toList() will return empty list when size of iterator is 1. In this case, iterator size is 1, return value of iterator.hasNext() is false, therefore, it will return empty list by default.
