objectify - java.lang.IllegalStateException: At path ** Expected property value

I have a below entity containing an EmbedMap, which in turn contains an Embed object. 

@Entity
public class Data
{
    @Id private long id;
    private String name;
    @EmbedMap Map<String, PlayerData> dataMap = Maps.newHashMap();
}

@Embed
public class PlayerData
{
    private long playerId;
    List<TurnData> turns = Lists.newArrayList();
}

@Embed
public class TurnData
{
    private long turnId;
    private long score;
}

When I try to save the Data entity into datastore using Objectify, I get the below exception (I am currently on objectify 4.0b3):

The format Objectify v4 uses to store embedded collections does not accommodate storing collections nested inside of collections. If you migrate to v5, you will be able to do this.
