--------------------------------
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.
