Current code is
ArrayList servers=MBeanServerFactory.findMBeanServer(null);
if(servers != null && servers.size() > 0) {
return (MBeanServer)servers.get(0);
}

This takes the first server it find. However, if we run JBoss (which has its own MBeanServer) inside of JDK 5 (which also has an MBeanServer), we have multiple servers. The code needs to be changes to accommodate that
