Subject [jira] Commented: (MYFACES-2840) Use a copied Iterator instead of the real Enumeration in AbstractAttributeMap.AbstractAttributeIterator
Date Thu, 23 Sep 2010 23:16:32 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-2840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12914277#action_12914277

Leonardo Uribe commented on MYFACES-2840:
-----------------------------------------

Finally I added a class called AbstractThreadSafeAttributeMap and this one is implemented
only for ApplicationMap and SessionMap.

> We can use a copied version of the Enumeration from getAttributeNames() here, because
directly using it might cause a ConcurrentModificationException  when performing remove().
Note that we can do this since the Enumeration from getAttributeNames() will contain exactly
the attribute names from the time getAttributeNames() was called and it will not be updated
if attributes are removed or added.
