Connection refused is not raising an exception

Question

Hi, I am having problems getting my code to recognise that a url refuses a connection, eg "http://tigers.com.au".
Opening the url in a browser correctly shows that a connection is refused.
However, in Java (1.6_07) code as below, no exception is raised, and the response code is 200 OK.
Even though no exception is raised, the content that is returned by the InputStream is actually from somewhere else (my local development server), so it seems that the connection is not actually successful.
The code works fine for other urls that does accept a connection, eg it works fine for "http://www.tigers.com.au".
Why is my code not raising an exception for cases where the url refuses a connection? Or is there a bug in Java?
Grateful for any help.
          BufferedReader in = null;
          String s=null;
          HttpURLConnection urlCon = null;
          URL url = null;
          try {
               url = new URL("http://tigers.com.au");
               urlCon = (HttpURLConnection) url.openConnection(); 
               urlCon.connect();
               System.out.println("urlCon after connect: "+urlCon.getURL());
                     System.out.println("Response code: ["+urlCon.getResponseCode()+"] "+urlCon.getResponseMessage());
               in = new BufferedReader( new InputStreamReader(urlCon.getInputStream()));
               while ( (s=in.readLine()) != null) {
                    System.out.println("s: "+s);                    
          catch (Exception e) {
               System.out.println("Exception: "+e);
          }

Have found that wildcard addresses matches any address of the local system, and that in IPv4, the wildcard address is 0.0.0.0. Can check for this with InetAddress.isAnyLocalAddress().
This means that I could potentially handle these cases by adding code to "ping" a host such as "tigers.com.au" using
InetAddress address = InetAddress.getByName(name);
if (InetAddress.isAnyLocalAddress() {
.... do something, eg raise exception
}But this is not fully satisfactory, as I would rather know that a "connection refused" exception is raised, which is actually the case with "tigers.com.au" (as all the browsers seem able to detect). I am not entirely sure what the relationship is between a site that has "connection refused" and it returning an ip address of 0.0.0.0. I don't think they are synonymous.
Any thoughts?
