Upgrade jboss remoting to 2.2.1.GA to incorporate some nice (and backwards compatible fixes):

JBREM-747: "org.jboss.remoting.transport.Connector should unregister server invoker from MBeanServer"
JBREM-748: "BisocketClientInvoker should guard agains scheduling on an expired Timer"
JBREM-751: "Eliminate unnecessary "Unable to process control connection:" message from BisocketServerInvoker"
JBREM-761: "NPE in BisocketServerInvoker$ControlConnectionThread"

Ron has also added a 2.2.1.GA <--> 2.2.0.SP4 compatibility test to the Remoting compatibility test suite. 2.2.1.GA is compatible back to 1.4.3.GA, which covers JBossAS 4.0.4, 4.0.5, and 4.2.0.

Thanks Ron.
