             Summary: RpcDispatcher : exclusion list failure
                 Key: JGRP-1630
                 URL: https://issues.jboss.org/browse/JGRP-1630
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.3
            Reporter: Karim AMMOUS
            Assignee: Bela Ban


The usage of exclusion list during RPC call is not thread safe. In some conditions, requests are executed on excluded members. 

Please find enclosed a program that reproduce the reported problem.

h5. Program scenario:
First statements create a permanent opened channel with an RpcDispacher.
The remaining represents a loop that creates a channel with an RpcDispatcher, makes an RPC call where exclusion list contains the caller and finally disconnects the channel.
The program stops when the request is handled on the caller. Few iterations are needed to reach it

h5. Observation:
At the called side, the exclusion list is checked by the RequestCorrelator ([instruction here|https://github.com/belaban/JGroups/blob/3.3/src/org/jgroups/blocks/RequestCorrelator.java#L356]). 
The condition that supposed ignore request fails because RequestCorrelator has a null local_addr
