AMFConnection never give exception,why?

Question

This is my simple code
import flex.messaging.io.amf.client.AMFConnection;
import flex.messaging.io.amf.client.exceptions.ClientStatusException;
public class AMFClient {   
    public AMFClient() {        
    public static void main(String[] args) {        
        AMFConnection amfConnection = new AMFConnection();
        String url = "http://192.168.0.199:9081/testApp/messagebroker/amf";       
        System.out.println("AMF Client Test");
        try
            amfConnection.connect(url);
        catch (ClientStatusException cse)
            System.out.println(cse);
            return;
The program never give exception if I give a non-existed url,why?Please help

If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.0.1. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily.  Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).
