>  Encountered an IllegalStateException while traversing with Flat3Map.entrySet()
> {code:java}
> //代码示例
>     public void testEntrySet() {
>         final Flat3Map<Integer, String> map = new Flat3Map<>();
>         map.put(1, "A");
>         map.put(2, "B");
>         map.put(3, "C");
>         Iterator<Map.Entry<Integer, String>> it = map.entrySet().iterator();        Map.Entry<Integer, String> mapEntry1 = it.next();
>         Map.Entry<Integer, String> mapEntry2 = it.next();
>         Map.Entry<Integer, String> mapEntry3 = it.next();
>         it.remove();        assertEquals(2, map.size());
>     }
> {code}
> Using the above code will generate an IllegalStateException.
> The reason for this problem is that there is a problem with the EntryIterator.remove() method in the Flat3Map java class.
> I submitted a [PR|https://github.com/apache/commons-collections/pull/115](https://github.com/apache/commons-collections/pull/115) to fix this bug.
