thrown in the line

     log.debug(this + " using pool (" + pool + ") already defined for " + address);

in org.jboss.remoting.transport.socket.MicroSocketClientInvoker.initPool().  pool is a java.util.LinkedList, and LinkedList.toString() iterates through the list elements.  These elements can be shared by multiple client invokers, and apparently another invoker modified the list while the log statement was running.
