Проблема десериализации из XML в POJO с Jackson: нет конструктора String-argument / Заводского метода для десериализации из строкового значения

у меня есть XML-документ, который мне нужно преобразовать (десериализовать) в Java POJO. Я!--10-->невозможно изменить структуру XML-документа. Я использую Java 8 и Jackson framework для отображения. ш зависимости:

dependencies {
    compile('com.fasterxml.jackson.dataformat:jackson-dataformat-xml')
    compile('org.springframework.boot:spring-boot-starter-freemarker')
    compile('org.springframework.boot:spring-boot-starter-web')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

XML Doc оболочки:

@JacksonXmlRootElement(localName = "rates_response")
public class RatesResponse implements Serializable{
    private static final long serialVersionUID = 3254688495454519L;

    @JacksonXmlProperty(isAttribute = true)
    private String b_number = "";

    @JacksonXmlProperty(isAttribute = true)
    private String l_premium = "";

    @JacksonXmlProperty(isAttribute = true)
    private String currency = "";

    @XmlElement(required = false)
    @JacksonXmlProperty
    private String c_b_relationship = null;

    @JacksonXmlProperty(isAttribute = true)
    private String n_of_p_loans = null;

    /*
     * Key: status_code
     * Key: status_explanation
     */
    @JacksonXmlElementWrapper
    private Map<String, String> message_status = null;

   // @XmlElement
    @JacksonXmlElementWrapper(useWrapping = false)
    private List<RateDetails> rate_details = null;

    public RatesResponse(){}
     //GETTERS/SETTERS
Child document (`List<RateDetails> rate_details = null;`):


@JacksonXmlRootElement(localName = "rate_details")
public class RateDetails implements Serializable {
    private static final long serialVersionUID = 324564684815158619L;

    private String r_reference = null;
    @JacksonXmlProperty
    private String n_of_p_days = null;
    @JacksonXmlProperty
    private String n_of_instalments = null;
    @JacksonXmlProperty
    private String n_rate = null;
    @JacksonXmlProperty
    private String p_p_available = null;

    @XmlElement(required = false)
    @JacksonXmlProperty
    private String i_overrider = null;//not always appears in doc
    @JacksonXmlProperty
    private String a_fee = null;
    @JacksonXmlProperty
    private String m_fee = null;
    @JacksonXmlProperty

    @JacksonXmlProperty
    private String t_c_for_credit = null;
    @JacksonXmlProperty
    private String d_amount = null;
    @JacksonXmlProperty
    private String apr = null;

    public RateDetails(){}
    //GETTERS/SETTERS

XML-документ для анализа:

<?xml version="1.0"?>
<!DOCTYPE rates_response SYSTEM "p_f_interface.dtd">

        <d_amount>0.00</d_amount>
        <apr>16.05</apr>
    </rate_details>    
</rates_response>

метод, который анализирует doc:

private RatesResponse readRatesDoc() {
    RatesResponse xmlContainer = null;

    ObjectMapper xmlMapper = new XmlMapper();
    try {
        xmlContainer = xmlMapper.readValue(contrUtil.readXmlFile("Rates_Response.xml"), RatesResponse.class);
    } catch (IOException e) {
        log.log(Level.SEVERE, "An Exception on parsing XML document", e);
    }
    return xmlContainer;
}

верхняя строка говорит:

no String-argument constructor/factory method to deserialize from String value ('16.05')

значение, на которое он ссылается, происходит из-под этого тега:

<apr>16.05</apr>

если я перемещаю (перемещаю) тег,<apr>16.05</apr>, парсер работает, и никаких исключений не возникает. Если я заменю тег другим тегом, то все равно произойдет то же исключение;это влияет только на последний тег в <rate_details> тег-обертка по каким-то причинам.

в чем проблема может быть?
