[jira] Updated: (COLLECTIONS-237) MultiValueMap: behavior of entrySet().iterator() is not the expected one

Henri Yandell updated COLLECTIONS-237:
--------------------------------------

    Fix Version/s:     (was: 3.3)
                   3.4

#1 gets the vote. On iterator....

Shouldn't the iterator() be returning a flattened iteration of values from all of the contained ArrayLists; and also be generating ConcurrentModificationException in some fun way?

I don't think this will be simple to implement, so pushing up to 3.4.

> The entrySet() method of the MultiValueMap delegates the entrySet() call to the decorated map, which is HashMap by default. The default hashmap iterator is used, which causes the iterator to return one Map.Entry for every key. The value returned for the key is an ArrayList, and not the value of the entry which was put into the map.
> The expected behavior would be the iterator to return the whole set of entries in the map, which requires iteration over the different array lists contained in the decorated map.
