Sebb commented on COLLECTIONS-330: ---------------------------------- The test testSynchronizedRemoveFromEntrySet also fails if one adds the following to the iterator loop: map.get(entry.getKey()); The problem is that get() has side effects. > ConcurrentModificationException using remove from the keySet the LRUMap > ----------------------------------------------------------------------- > > Key: COLLECTIONS-330 > URL: https://issues.apache.org/jira/browse/COLLECTIONS-330 > Project: Commons Collections > Issue Type: Bug > Components: Collection > Affects Versions: 3.3 > Reporter: Joerg Schaible > > Even if the access to a LRUMap is synced and the remove method of the > iterator is used that has been returned from the keySet of the LRUMap, it is > possible to get a ConcurrentModificationException. This does not happen for > remove of the iterators returned by the entrySet or values of the LRUMap.
