Jackson fails to convert Java pojo to XML

Question

I am trying to serialize a class Pojo to XML with Jackson XML mapper. Here is how the XML looks and i represented with objects, also:

XML

            <Class>
                    <ClassStudent Type="20">
                        <Student Age="2" Id="2">5.18</Student>
                        <Student Age="1" Id="1">4.863</Student>
                    </ClassStudent>
                    <ClassStudent Type="226">
                        <Student Age="3" Id="6" SpecialExpression="Good">1.91</Student>
                        <Student Age="1" Id="7" SpecialExpression="Prospective">1.89</Student>
                    </ClassStudent>
                </Class>

OBJECT

                    public class Class{
                    
                    @JsonProperty("ClassStudent")
                    private List<ClassStudent> classStudents;
                
                    }
                    
                    public class ClassStudent{
                    
                    @JsonProperty("Type")
                    private String type;
                    
                    @JsonProperty("Student")
                    private List<Student> student;
                    }
                    
                    public class Student{
                    
                    @JsonProperty("Age")
                    private String age;
                    
                    @JsonProperty("Id")
                    private String id;
                    
                    @JsonInclude(JsonInclude.Include.NON_NULL)
                    @JsonProperty("SpecialExpression")
                    private String specialExpression;
                    
                    private Double evaluation;
                    
                    }

I get an unrecognized field on Student level, not recognized field "Age"....
