I am trying to upgrade some opentracing libraries to use the drivers 4.0.x, in particular this project (https://github.com/opentracing-contrib/java-mongo-driver and this project (https://github.com/opentracing-contrib/java-spring-cloud).

They stopped working because they are based on this code:

if (bean instanceof MongoClient && !(bean instanceof TracingMongoClient)) {
  final MongoClient client = (MongoClient) bean;

  final TracingCommandListener commandListener = new TracingCommandListener.Builder(tracer).build();

  return new TracingMongoClient(commandListener, client.getServerAddressList(), 
                                                         client.getCredential(), 
                                                         client.getMongoClientOptions());
 }

 
But in the version 4.0.5 the method `client.getServerAddressList()` is not available anymore.

If I have the client, how am I supposed now to retrieve the list of the addresses?

The final goal is being able to have a (new?) MongoClient with a command listener, starting from a "naked" MongoClient. Is there any other way of doing that?
