[ http://issues.apache.org/jira/browse/JAMES-302?page=all ]
Stefano Bagnara updated JAMES-302:
----------------------------------
Fix Version: 2.3.0
(was: 2.1.3)
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pretty thoroughly been replaced by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;
