> Key: JAMES-302
> URL: http://issues.apache.org/jira/browse/JAMES-302
> Project: James
> Issue Type: Bug
> Components: DNSServer
> Affects Versions: Trunk
> Environment: Tested on WIN2000, JDK 1.4.1_01-b01
> Reporter: Steve Brewin
> Assigned To: Norman Maurer
> Priority: Minor
> Fix For: Trunk
>
>
> 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 This is a critical issue as in v2.2.0 java.net.InetAddress.getByName() has pretty thoroughly been replaced by org.apache.james.dnsserver.DNSServer.getByName(), but in the noted circumstances it doesn't perform the same.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;
