[jira] [Resolved] (COLLECTIONS-556) Add an IdentityHashSet

     [ https://issues.apache.org/jira/browse/COLLECTIONS-556?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Neidhart resolved COLLECTIONS-556.
-----------------------------------------
       Resolution: Fixed
    Fix Version/s: 4.1

Added new method SetUtils.identityHashSet in r1681635.

After updating to Java 6, we can use Collections.newSetFromMap to wrap an IdentityHashMap.

> The default JDK does not provide an IdentityHashSet which can be quite handy sometimes.
> collections already has a MapBackedSet, so we could easily provide one by wrapping an IdentityHashMap.
