java-cassnadra object Frozen annotation for address map<text, frozen<list<frozen<address>>>>,

Question

I am trying to insert data into Cassandra(2.1.9) My Java object has a map of a list of UDT. On running the code I am getting error regarding @Frozen annotation. I am using DataStax(2.1.9) Library. http://docs.datastax.com/en/drivers/java/2.1/index.html?com/datastax/driver/mapping/annotations/FrozenValue.html

create table user{
        name text,
        addresses map<text, frozen<list<frozen<address>>>>,
}

My Java Class

public class User{
    private String name;
    @FrozenValue
    private Map<String, List<AddressUDT>> addresses;
}

But I am getting following error

java.lang.IllegalArgumentException: Error while checking frozen types on field addresses of entity com.dante.data.model.User: expected AddressUDT to be frozen but was not frozen

@Frozen("map<text, frozen<list<frozen<AddressUDT>>>>")
private Map<String, List<AddressUDT>> addresses;
