             Summary:  Encountered an IllegalStateException while traversing with Flat3Map.entrySet()
                 Key: COLLECTIONS-734
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-734
             Project: Commons Collections
          Issue Type: Bug
          Components: Map
    Affects Versions: 3.0
            Reporter: Chen


 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.
