Use below set of lines while making connection to mongo db for resolving the issue with codec, while using POJO class in mongo.

ConnectionString connectionString = new ConnectionString("mongodb://" + username + ":" + password + "@" + host + ":" + port);
CodecRegistry pojoCodecRegistry = fromProviders(PojoCodecProvider.builder().automatic(true).build());
CodecRegistry codecRegistry = fromRegistries(MongoClientSettings.getDefaultCodecRegistry(), pojoCodecRegistry);

MongoClientSettings clientSettings = MongoClientSettings.builder()
                .applyConnectionString(connectionString)
                .codecRegistry(codecRegistry)
                .build();
MongoClient mongoClient = MongoClients.create(clientSettings);
MongoDatabase mongoDatabase = mongoClient.getDatabase(database);
