Brian Stansberry reopened JBCACHE-913:
--------------------------------------

             
Reopening, as I realize the fix I implemented doesn't provide the information about the number of key/value pairs that's needed by some  EvictionPolicy impls.  Solving that is going to require doing the notification in the StateTransferIntegrator (which is better anyway :).

>      Security Level: Public(Everyone can see) 
>    Affects Versions: 1.4.0.GA, 1.4.0.SP1, 2.0.0.ALPHA1
>            Reporter: Brian Stansberry
>         Assigned To: Brian Stansberry
>             Fix For: 1.4.1.GA

>   Original Estimate: 4 hours
>  Remaining Estimate: 4 hours

> When state transfer creates new nodes and adds them to the tree, any eviction policy is unaware of the addition.  As a result, those nodes are ignored for eviction unless they are accessed.
> This is a side effect of the addition of the EvictionInterceptor in 1.4.0.  The state transfer code generates TreeCacheListener node addition events, but with the EvictionInterceptor, the eviction policies are no longer listening for the events.
> Probable solution is to modify notifyAllNodesCreated to have it find any eviction region for any nodes it has added.  Then have it generate an EvictedEventNode and pass it to Region.putNodeEvent.
