NamingContext does not take potential AutoDiscoveryAddress XML property overrides when sending discovery requests
-----------------------------------------------------------------------------------------------------------------

                 Key: JBAS-4604
                 URL: http://jira.jboss.com/jira/browse/JBAS-4604
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering, Naming
    Affects Versions: JBossAS-4.2.1.GA, JBossAS-5.0.0.Beta2, JBossAS-4.0.5.GA
            Reporter: Galder Zamarreno
         Assigned To: Brian Stansberry
            Priority: Minor


Bug in org.jnp.interfaces.NamingContext:

discoverServer(Hashtable) method

String group = DEFAULT_DISCOVERY_GROUP_ADDRESS;
...
String discoveryGroup = (String) serverEnv.get(JNP_DISCOVERY_GROUP);
if (discoveryGroup != null)
group = discoveryGroup;
...
iaGroup = InetAddress.getByName(group);
....
if (trace)
log.trace("Sending discovery packet(" + data + ") to: " + iaGroup + ":" + port);

NamingContext code does not take in account possible system property overrides
coming from:

<attribute name="AutoDiscoveryAddress">${jboss.partition.udpGroup:230.0.0.4}</attribute>

AutoDiscoveryAddress used to send discovery messages is controlled via the the
default value, 230.0.0.4 or jnp.discoveryGroup property. 

So, if user sets jboss.partition.udpGroup=224.0.0.1 on startup, 
DetachedHANamingService$AutomaticDiscovery will listen on 224.0.0.1 while 
NamingContext sends discovery requests to 230.0.0.4
