Why does id of child entity return 0 in response message in EclipseLink? - jpa

Question

I'm using a One-To-One association between my Member and MemberRoles tables. I wanted them to share the same id as PK and FK in the database and did it. But I've got another problem. When I insert a Member, a MemberRole record is being inserted with it and Member record has the correct id in return response but MemberRole id is incorrect. It returns 0 like this:
{
"result": "Bulk user member saving is successfull. Members' informations are:",
"memberList": [
{
"id": 2,
"firstName": "Michael",
"lastName": "Schumacher",
"email": "ilkay.gune2l#kod5.org",
"enabled": false,
"memberLanguageCode": "tr",
"roleOfMember": {
"id": 0,
"email": "ilkay.gune2l#kod5.org",
"role": "ROLE_USER"
}
}
]
}
My Member Entity Class:

public String toString() {
return String.format("Member [id=%d, firstName='%s', lastName='%s', email='%s']", id, firstName, lastName,
email);
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
if (null != roleOfMember) {
roleOfMember.setId(id);
}
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {

}
public String getLastName() {

public void setLastName(String lastName) {

public String getEmail() {

public void setEmail(String email) {

public boolean isEnabled() {

}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public MemberRoles getRoleOfMember() {
return roleOfMember;
}
public void setRoleOfMember(MemberRoles roleOfMember) {
this.roleOfMember = roleOfMember;
}
public String getActivationToken() {
return activationToken;
}
public void setActivationToken(String activationToken) {
this.activationToken = activationToken;
}
public LocalDateTime getActivationTokenExpDate() {
return activationTokenExpDate;

public void setActivationTokenExpDate(LocalDateTime activationTokenExpDate) {

}
public String getMemberLanguageCode() {
return memberLanguageCode;
}
public void setMemberLanguageCode(String memberLanguageCode) {
this.memberLanguageCode = memberLanguageCode;
}
}
And my MemberRoles Entity class:
package com.ilkaygunel.entities;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.MapsId;

import javax.persistence.NamedQuery;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import com.fasterxml.jackson.annotation.JsonIgnore;
#Entity
#NamedQueries({

#Table(name = "MEMBERROLES")
public class MemberRoles {
#Id
#Column(name = "MEMBERROLES_ID")
private long id;
private String email;
private String role;
#MapsId
#OneToOne(optional = false)
#JoinColumn(name = "MEMBERROLES_ID", unique = true, nullable = false, updatable = false)
#JsonIgnore
private Member member;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public Member getMember() {
return member;
}
public void setMember(Member member) {
this.member = member;
}
}
When I inserted a Member record, I check it on the database and see that Member and MemberRoles record have the same id. But why does MemberRoles area in response message has got id as 0?
