> Any call to InetAddress.getHostName() will cause a reverse DNS lookup. If DNS is not configured properly, can cause slow startup/join times between JBoss clusters.
> The most notable is in ClusterNode.java: 
> public ClusterNode(IpAddress jgAddress) 
> { 
>    if (jgAddress.getAdditionalData() == null) 
>    { 
>       this.id = jgAddress.getIpAddress().getHostAddress() + ":" + jgAddress.getPort(); 
>    } 
>    else 
>    { 
>       this.id = new String(jgAddress.getAdditionalData()); 
>    } 
>    this.originalJGAddress = jgAddress; 
>    StringBuffer sb = new StringBuffer(); 
>    java.net.InetAddress jgIPAddr = jgAddress.getIpAddress(); 
>    if (jgIPAddr == null) 
>       sb.append("<null>"); 
>    else 
>    { 
>       if (jgIPAddr.isMulticastAddress()) 
>          sb.append(jgIPAddr.getHostAddress()); 
>       else 
> ----->>>> sb.append(getShortName(jgIPAddr.getHostName())); 
>    } 
>    sb.append(":" + jgAddress.getPort()); 
>    this.jgId = sb.toString(); 
> } 
> The following: 
> if (jgIPAddr.isMulticastAddress()) 
>    sb.append(jgIPAddr.getHostAddress()); 
> else 
>    sb.append(getShortName(jgIPAddr.getHostName())); 
> should be replaced with: 
> sb.append(jgIPAddr.getHostAddress());
