[jira] Created: (HARMONY-56)
java.net.InetAddress.getAllByName(null) throws UnknownHostException instead
of valid InetAddress
java.net.InetAddress.getAllByName(null) throws UnknownHostException instead of valid InetAddress
------------------------------------------------------------------------------------------------
Key: HARMONY-56
URL: http://issues.apache.org/jira/browse/HARMONY-56
Project: Harmony
Type: Bug
Components: Classlib
Reporter: Svetlana Samoilenko
According to j2se 1.4.2 specification java.net.InetAddress.getAllByName(String host) method allows a host is null. In this case the InetAddress representing an address of the loopback interface is returned.
But as we can see from the test listed below java.net.InetAddress.getAllByName(null) throws UnknownHostException instead of valid InetAddress.
Code to reproduce:
import java.net.*;
public class test2 {
public static void main (String[] args) {
try {
InetAddress[] ia = InetAddress.getAllByName(null);
for (int i = 0; i<ia.length; i++) {
System.out.println("***InetAddress.getAllByName(null)["+i+"] returned " + ia[i]);
}
} catch (Exception e) {
System.out.println("***Unexpected exception:" + e);
}
}
}
Steps to Reproduce:
1. Build Harmony (check-out on 2006-01-30) j2se subset as described in README.txt.
2. Compile test2.java using BEA 1.4 javac
> javac -d . test2.java
3. Run java using compatible VM (J9)
> java -showversion test2
Output:
C:\tmp>C:\jrockit-j2sdk1.4.2_04\bin\java.exe -showversion test2
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
BEA WebLogic JRockit(TM) 1.4.2_04 JVM (build ari-31788-20040616-1132-win-ia32, Native Threads, GC strategy: parallel)
***InetAddress.getAllByName(null)[0] returned localhost/127.0.0.1
C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2
(c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as applicable.
***Unexpected exception:java.net.UnknownHostException: No host name provided
Suggested junit test case:
------------------------ InetAddressTest.java -------------------------------------------------
import java.net.*;
import junit.framework.*;
public class InetAddressTest extends TestCase {
public static void main(String[] args) {
junit.textui.TestRunner.run(InetAddressTest.class);
}
public void test_getAllByName() {
try {
InetAddress[] ia = InetAddress.getAllByName(null);
assertEquals ("Assert 0: getAllByName() returns incorrect value " + ia[0].toString(),"localhost/127.0.0.1",ia[0].toString());
} catch (Exception e) {
fail("Assert 1: Unexpected exception:" + e);
}
}
}

--------------------------------------------
Tim,
I used revision 375576 and all works fine.
Test output is:
***InetAddress.getAllByName(null)[0] returned localhost/127.0.0.1
Thank you.
