             Summary: KeyAffinityService race condition on view change
                 Key: ISPN-5568
                 URL: https://issues.jboss.org/browse/ISPN-5568
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 5.2.11.Final
            Reporter: Dennis Reed


KeyAffinityService#getKeyForAddress runs in a tight loop looking for keys:

    queue = address2key.get(address)
    while (result == null)
        result = queue.poll()

KeyAffinityService#handleViewChange clears and resets the queue list on membership change:

    address2key.clear()
    for each address
        map.put(address, new queue)

If a view change comes in after getKeyForAddress gets the queue, and the queue is empty, it will get stuck in tight loop looking at the wrong queue forever while new keys are added to the new queue.
