java - Unmarshaller 在简单的 XML 字符串解析中抛出 IllegalAccessError

Question

我想在以 open-liberty 运行的 java EE 应用程序中使用javax.xml.bind.Unmarshaller将简单的 xml 字符串反序列化为对象。我有以下反序列化方法：

反序列化

package com.my.deserializer;

public class XmlDeserializer {
    private static Name deserialize() {
        try {
            JAXBContext jaxbContext = JAXBContext.newInstance(Name.class);
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();           

            StringReader reader = new StringReader("<Name xml:lang=\"en\">Acme, Inc.</Name>");
            Name cXml = (Name) unmarshaller.unmarshal(reader);
            return cXml;
        } catch (JAXBException e) {
            e1.printStackTrace();
        }
        return null;
    }
}

班级

package com.my.model;

@XmlRootElement(name = "Name")
public class Name implements Serializable {
    private static final long serialVersionUID = -4018453444627994825L;

    @XmlAttribute(name = "lang", namespace = "xml")
    public String lang;
    
    @XmlValue
    public String text;
}

当我打电话时XmlDeserializer.deserialize()，我得到以下异常：

java.lang.IllegalAccessError: tried to access class com.my.model.Name from class com.my.deserializer.XmlDeserializer

Name如果我将类名从更改为任何其他名称 ex ，我只能使此代码正常工作Name_Entity。我的代码有什么问题吗？
