Subject [jira] Commented: (COLLECTIONS-330) ConcurrentModificationException using remove from the keySet the LRUMap
Date Thu, 18 Jun 2009 14:59:07 GMT

    [ https://issues.apache.org/jira/browse/COLLECTIONS-330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721287#action_12721287
] 

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.

> 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. See currently not executed unit test in TestLRUMap (marked as TODO for COLLECTION-3).
