Класс имеет два свойства с одинаковым именем "address1"

Question

Я хочу создать объект JAXB, используя следующий код:

@XmlRootElement(name = "payment_transaction")
@XmlAccessorType(XmlAccessType.FIELD)
public class AuthorizeRequest {

    @XmlElement(name = "transaction_type")
    public String transaction_type;

    @XmlElement(name = "transaction_id")
    public String transaction_id;

    .......

    public String getTransaction_type() {
        return transaction_type;
    }

    public void setTransaction_type(String transaction_type) {
        this.transaction_type = transaction_type;
    }

    public String getTransaction_id() {
        return transaction_id;
    }       
}

Внутренний объект:

public class Address {

    @XmlElement(name = "first_name")
    public String firstName;

    @XmlElement(name = "last_name")
    public String lastName;

    ... getters and setters
}

Но я получаю ошибку:

2019-06-23 11:43:10,495 ERROR [stderr] (AuthorizeContainer-1) Class has two properties of the same name "address1"
2019-06-23 11:43:10,496 ERROR [stderr] (AuthorizeContainer-1)   this problem is related to the following location:
2019-06-23 11:43:10,496 ERROR [stderr] (AuthorizeContainer-1)       at public java.lang.String authorize.request.Address.getAddress1()
2019-06-23 11:43:10,496 ERROR [stderr] (AuthorizeContainer-1)       at authorize.request.Address
2019-06-23 11:43:10,496 ERROR [stderr] (AuthorizeContainer-1)       at public request.Address AuthorizeRequest.billingAddress

DoВы знаете, как я могу решить эту проблему?Нужно ли добавлять аннотации для класса Address?
