If an exception is thrown in #handle the connection will not be deleted, despite being handled. This can cause ghost connections.

           @Override 
        
           public final void handle(final HttpExchange exchange) throws IOException{ 
        
               if(throttler.addConnection(exchange)){ 
        
                   handler.handle(exchange); 
        
                   throttler.deleteConnection(exchange); 
        
               }else{ 
        
                   exchange.close(); 
        
               } 
        
           }

Expected Behavior

Explain what was supposed to happen

Connections should be deleted after handle (use a try finally).

Steps To Reproduce

Explain how and/or when the error occurred

Throw an exception in throttled handler.

	@Override
	public final void handle(final HttpExchange exchange) throws IOException{
	if(throttler.addConnection(exchange)){
	handler.handle(exchange);
	throttler.deleteConnection(exchange);
	}else{
	exchange.close();
	}
	}
