RankCalculatorListener registered to late

Any call to HotRod Server v. 4.2.0.ALPHA3 ends with the exception:

2010-10-14 17:39:36,953 ERROR [org.infinispan.server.core.AbstractProtocolDecoder$] (HotRodServerWorker-1-22) Exception reported

The reason is that RankCalculatorListener is registered to late - in org.infinispan.server.core.start() method, which is called at the end of overriding org.infinispan.server.hotrod.HotRodServer.start(), which in turn starts all the defined caches.
Maybe there is a need for adding a new lifecycle method to ProtocolServer - create(). Like in JMX services.
