Loopback addresses in the range 127.0.0.2 - 127.255.255.255 should be supported

When starting JBoss like this: "standalone.sh -b 127.0.0.2 -c standalone-ha.xml", the startup fails because 127.0.0.2 cannot be resolved.
However, a loopback address should be recognized even if it doesn't resolve to an interface. The code below works for example:

InetAddress addr=InetAddress.getByName("127.0.0.5");
boolean is_loopback=addr.isLoopback(); // should be true

Loopback addresses are very useful for local testing, ie. starting of multiple JBoss instances on the same box.
