Here is an overview of the issue:
---------------------------------------------------------------------
        Key: JAMES-302
    Summary: Functionality of org.apache.james.dnsserver.DNSServer.getByName(String) is not
symetric to java.net.InetAddress.getByName(String)
       Type: Bug

     Status: Unassigned
   Priority: Critical

    Project: James
 Components: 
             DNSServer
   Versions:
             2.2.0

   Assignee: 
   Reporter: Steve Brewin

    Created: Tue, 6 Jul 2004 2:43 PM
    Updated: Tue, 6 Jul 2004 2:43 PM
Environment: Tested on WIN2000, JDK 1.4.1_01-b01

Description:
org.apache.james.dnsserver.DNSServer.getByName(String) does not always return the same result
as java.net.InetAddress.getByName(address). Sometimes an exception is thrown when the standard
implementation does not.

When passed a fully qualified domain name the results are the same. When passed a hostname
or the special name 'localhost', a java.net.UnknownHostException is thrown by org.apache.james.dnsserver.DNSServer
while java.net.InetAddress resolves the addresses correctly.

This is a critical issue as in v2.2.0 java.net.InetAddress.getByName() has pretty thoroughly
been replaced by org.apache.james.dnsserver.DNSServer.getByName(), but in the noted circumstances
it doesn't perform the same. Dependent code breaks.

Here are the contrasting examples...

// FAILS
String address = "localhost";
java.net.InetAddress inetAddress = org.apache.james.dnsserver.DNSServer.getByName(address);
return inetAddress;

// FAILS
String address = "hostname";
java.net.InetAddress inetAddress = org.apache.james.dnsserver.DNSServer.getByName(address);
return inetAddress;

// SUCCEEDS
String address = "localhost";
java.net.InetAddress inetAddress = java.net.InetAddress.getByName(address);
return inetAddress;

// SUCCEEDS
String address = "hostname";
java.net.InetAddress inetAddress = java.net.InetAddress.getByName(address);
return inetAddress;
