> 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. 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)
> ***OK. UnknownHostException=:java.net.UnknownHostException: addr is of
> illegal length
> C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2

> java.lang.NullPointerException
> at java.net.InetAddress.getByAddress(InetAddress.java:735)
> at java.net.InetAddress.getByAddress(InetAddress.java:713)
> at test2.main(test2.java:7)
> 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_getByAddress() {
> try {
> InetAddress.getByAddress (null);
> fail("Assert 0: UnknownHostException must be thrown");
> } catch (UnknownHostException e) {
> }
> }
> }
