The connection pool mbean is generated automatically when the *-ds.xml file is parsed, so you might be better off modifying the existing one than trying to wrap or replace it. I think that the connection pool manager is in the source at connector/src/main/org\jboss/resource/connectionmanager/InternalManagedConnectionPool.java (this is a guess, the actual connector is hidden behind an interface - see the poolingStrategy field in the JBossManagedConnectionPool class in the same directory. Alternately, you could turn on TRACE level logging for the InternalManagedConnectionPool class, it seems to do some logging regarding connection requests at that level.
