Can the cache be backed by LinkedHashSet instead of HashSet
-----------------------------------------------------------

                 Key: JBCACHE-1214
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-1214
             Project: JBoss Cache
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
         Environment: RFC
            Reporter: Carl Shelbourne
         Assigned To: Manik Surtani
            Priority: Optional


Looking at the code it is noted that the cache is backed by a HashSet. 

Would it be possible to change this so that it is backed by a LinkedHashSet.

There may or may not be performance benefits to this dependant on the usage. The primary reason for wanting it to be backed by a LinkedHashSet is the guaranteed ordering of the elements when iterated over. Having this guarantee would facilitate implementations of say a TableModel, but would make other iterations more predictable too.
