Svetlana Samoilenko commented on HARMONY-61: -------------------------------------------- Tim, I used revision 375338 and the problem resolved as expected. Output is: ***OK. Expected UnknownHostException. java.net.UnknownHostException: Invalid IP Address is neither 4 or 16 bytes Thanks a lot for quick response. > java.net.InetAddress.getByAddress(null) throws NPE insread of > UnknownHostException > ---------------------------------------------------------------------------------- > > Key: HARMONY-61 > URL: http://issues.apache.org/jira/browse/HARMONY-61 > Project: Harmony > Type: Bug > Components: Classlib > Reporter: Svetlana Samoilenko > Assignee: Tim Ellison > > According to j2se 1.4.2 specification for > java.net.InetAddress.getByAddress(byte[] addr) the method must throw > UnknownHostException if IP address is of illegal length. IPv4 address byte > array must be 4 bytes long and IPv6 byte array must be 16 bytes long. There > is no mention about NPE at all. Mentions about NPE in case of null argument > were not found in java.net package specification. > The test listed below shows that getByAddress (null) throws NPE. BEA throws > UnknownHostException. > Code to reproduce: > import java.net.*; > public class test2 { > public static void main (String[] args) { > > try { > InetAddress.getByAddress (null); > } catch (UnknownHostException e) { > System.out.println("***OK. Expected UnknownHostException. " + e); > } > } > } > Steps to Reproduce: > 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in > README.txt. > 2.
