InetAddress - is it broken??

I have a similar problem with InetAddress.getLocalHost(). I don't
think, however, that the GCJ implementation is bugged. It's simply one
of these very confused APIs in the JDK (just as java.util.Date is
"confused")
I've solved it temporarily in the following way:
		InetSocketAddress inetAddress=
			(InetSocketAddress)socket.getRemoteSocketAddress();
		String hostName=inetAddress.getAddress().getCanonicalHostName();
		String remoteMachine=null;
		if(hostName.equals("localhost"))
			try
			{
				remoteMachine=InetAddress.getLocalHost().getHostName();
			}
			catch(UnknownHostException e)
			{
				inetAddress.getHostName();
			}
		else remoteMachine=inetAddress.getHostName();
I'm trying to create a utility that will do message queueing with
org.apache.xmlrpc invokations; and I need to keep track of the address
of the client machine, in order to send back results to the sender.
