serviceResolved called infinitely for a single service registration

[funkcjonusz]

Taking ServiceInfo using the following implementation causes the serviceResolved method to be called continuously(infinitely) for single service registration:
`

class SampleListener implements ServiceListener {

       @Override   
       public void serviceResolved(ServiceEvent event) {  
           String deviceInfo = (event.getDNS().getServiceInfo(event.getType(), event.getName())).getNiceTextString();  
                                     
           ...                  
       }             
    }  
    `

If I use the implementation shown below I see one or two calls of serviceResolved method for single service registration but only last one has proper string/message describing service
`
ServiceInfo serviceInfo = event.getInfo();
String deviceInfo = new String(serviceInfo.getTextBytes());

`
Why does the last call of serviceResolved method has the correct message?
