How are you getting the Test-IP? It looks like you just did a
toString() on the InetAddress object. That method returns the host
name (assuming it can reverse lookup the name) along with the address.
(localhost is the reverse lookup on your system for 127.0.0.1 - and
it is that for most systems)

This is not a bug in the JDK - you may wish to look at the getHostAddress()
method which will return a string of just the address.
See the java.net.InetAddress JavaDOCs for details.
