Demonstrate how to add multiple codecs to the default registry.

CodecTest.java

import com.mongodb.MongoClient;
import com.mongodb.MongoClientOptions;
import com.mongodb.ServerAddress;
import org.bson.Document;
import org.bson.UuidRepresentation;
import org.bson.codecs.UuidCodec;
import org.bson.codecs.configuration.CodecRegistry;

import java.util.UUID;

import static org.bson.codecs.configuration.CodecRegistries.fromCodecs;
import static org.bson.codecs.configuration.CodecRegistries.fromRegistries;

public class CodecTest {
    public static void main(String[] args) {
        MongoClientOptions.Builder builder = MongoClientOptions.builder();
        CodecRegistry codecRegistry = fromRegistries(fromCodecs(new UuidCodec(UuidRepresentation.STANDARD),
                                                                new SqlDateCodec()),
                                                     MongoClient.getDefaultCodecRegistry());

        builder.codecRegistry(codecRegistry);
        MongoClientOptions options = builder.build();
        MongoClient client = new MongoClient(new ServerAddress(), options);

        client.getDatabase("test").getCollection("test").insertOne(new Document("_id", UUID.randomUUID())
                                                                  .append("date", new java.sql.Date(System.currentTimeMillis())));

    }
}

Note that the SqlDateCodec referenced above is not included in the driver. It's just there as an example of how you can write your own Codec implementation
