Subject [jira] Commented: (HARMONY-60) java.net.URL.getHost() must return the IPv6 address enclosed in square brackets
Date Tue, 07 Feb 2006 12:09:00 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-60?page=comments#action_12365424 ] 

Svetlana Samoilenko commented on HARMONY-60:
--------------------------------------------

Tim, 
I used revision 375380 and the IP6 address in [ ] now. 
Test output is: 
**OK, host is in square brackets=[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]

Actually, it is BEA bug, they assume that,  for example, "http://google.com/" is a IPV6 address,
presumably because it contains ':'.
it is just incorrect host address, but URL should not complain unlike URI. 
It would be better to check that it is real correct IP6 address, but may be we should copy
all BEA bugs for compatibility ;) ?

> According to j2se 1.4.2 specification for java.net.URL.getHost() the method must return
 the IPv6 address enclosed in square brackets ('[' and ']'). The test listed below shows an
absence of square brackets for the IPv6 address.
> Code to reproduce: 
> import java.net.*; 
> public class test2  {
>     public static void main(String[] args) {
>        
>      URL url=null; 
>      String protocol = "http";
>      int port = -1; 
>      String host = "FEDC:BA98:7654:3210:FEDC:BA98:7654:3210";
>      String file = "myFile";
>     
>      try {
>             url = new URL(protocol,host,port,file); 
>      } catch (Exception e) {
>             System.out.println("URL.URL(protocol,host,port,file) caused:" + e); 
>             return; 
>      }
>      if (url.getHost().equals("["+host+"]")) {
>            System.out.println("OK, host is in square brackets="+url.getHost());
>      } else {
>            System.out.println("Incorrect, host is not in square brackets="+url.getHost());
>      }
>   }
> }
> 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)
