Creating a new CassandraClientOptions for another instance doesn't work

[mafa73]

Version

3.8.5

Context

It isn't possible to create a new CassandraClientOptions instance base on another CassandraClientOptions instance if the addContactPoints has been used on the original.

Do you have a reproducer?

public static void main(String[] args) {
     Vertx vertx = Vertx.vertx();
     try {
         CassandraClientOptions cassandraClientOptions = new CassandraClientOptions().addContactPoint("127.0.0.1");
         CassandraClientOptions cassandraClientOptionsCopy = new CassandraClientOptions(cassandraClientOptions);
     } finally {
         vertx.close();
     }
 }

Exception is thrown when cassandraClientOptionsCopy is created:
