Azure Event Hubs WebSockets and Proxy support

Shubha Vijayasarathy - I am getting CommunicationException when I tried to implement EventHub Publish with Proxy settings.

EventHub SDK Version - com.microsoft.azure:azure-eventhubs:3.2.2

Below is the Implementation details:

public void sendEvent(VinData vinData) throws EventHubException, ExecutionException, InterruptedException, IOException{
   
   // step-1: set the proxy server settings
   ProxySelector.setDefault(new ProxySelector() { 
@Override
   public List<Proxy> select(URI uri) { 
   LinkedList<Proxy> proxies = new LinkedList<>(); 
   proxies.add(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("19.12.64.237", 83))); 
   proxies.add(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("19.12.80.237", 83))); 
   proxies.add(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("19.12.16.64", 83))); 
   proxies.add(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("19.12.32.11", 83))); 
   return proxies; 
   }
   
   @Override 
   public void connectFailed(URI uri, SocketAddress sa, IOException ioe) { 
   // trace and follow up on why proxy server is down 
   }
   }); 
   
      ScheduledExecutorService executorService1 = Executors.newScheduledThreadPool(5); 

   EventHubClient evHubClient = EventHubClient.createFromConnectionStringSync(new ConnectionStringBuilder(config.getFfmEvHubConnectionString())
              .setTransportType(TransportType.AMQP_WEB_SOCKETS).toString(),
              executorService1);
log.info("#VinData ==> "+vinData.getBody().getVin());
log.info("#ProxyConfig Configured? =>"+proxyConfig1.isProxyAddressConfigured());
log.info("#Proxy Config ==> Address ==> "+proxyConfig1.proxyAddress().address());

   try {
   
      log.info("VinData ==> "+vinData.getBody().getVin());
      
      byte[] bytes = SerializationUtils.serialize(vinData);

       log.info("Sending message from FFM VInData to the event hub {}", config.getFfmEvHubName());
      
   
   EventData ffmEventData = EventData.create(bytes);
   
   log.info("FFM Event Data ::"+ffmEventData.toString());

   √.sendSync(ffmEventData);

   
   }finally {
   evHubClient.closeSync();
          //executorService.shutdown();
      }
      
  }

 The above code execution is throwing the below mentioned exception:
