Subject [jira] Created: (HARMONY-60) java.net.URL.getHost() must return the IPv6 address enclosed in square brackets
Date Wed, 01 Feb 2006 05:00:32 GMT
java.net.URL.getHost() must return the IPv6 address enclosed in square brackets
-------------------------------------------------------------------------------

         Key: HARMONY-60
         URL: http://issues.apache.org/jira/browse/HARMONY-60
     Project: Harmony
        Type: Bug
  Components: Classlib  
    Reporter: Svetlana Samoilenko


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) 
BEA WebLogic JRockit(TM) 1.4.2_04 JVM (build ari-31788-20040616-1132-win-ia32, Native Threads,
GC strategy: parallel) 
***OK, host is in square brackets=[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]

C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2

***Incorrect, host is not in square brackets=FEDC:BA98:7654:3210:FEDC:BA98:7654:3210

Suggested junit test case:
------------------------ URLTest.java ------------------------------------------------- 
import java.net.*; 
import junit.framework.*; 

public class URLTest extends TestCase { 
    public static void main(String[] args) { 
        junit.textui.TestRunner.run(URLTest.class); 
    } 
    public void test_getHost() { 
        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) {
            fail("Assert 0: URL.URL(protocol,host,port,file) caused:" + e); 
        }
       assertEquals (("["+host+"]"), url.getHost());
   } 

}
