Additional query was run though it is not part of the select statement

Question

I have created two Entity Java file which indicate there are two tables, User and UserPasswordHistory, UserPasswordHistory has ManyToOne Relationship to user table, whenever i select UserPasswordHistory by the foreign key userid, it will select the User table as well.

The library i am using to test the JPA is \EclipseLink 2.5.2 and the link is the libraries which come with EclipseLink 2.5.2Libraries List

I have defined the @ManyToOne (fetch=FetchType.LAZY), but the issue is persist

User.java

@Entity
@Table(name="Users")
public class User {


     @Id
     @GeneratedValue( strategy= GenerationType.AUTO ) 
     private int userId;
     private String username;
     private String passowrd;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUsername() {
        return username;
    }

....

UserPasswordHistory.java

@Entity
public class UserPasswordHistory {

     @Id
     @GeneratedValue( strategy= GenerationType.AUTO )   

     private long historyId;
     private String password;
     private User user;


     public long getHistoryId() {
        return historyId;
    }
    public void setHistoryId(long historyId) {
        this.historyId = historyId;
    }

    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

    @ManyToOne (fetch=FetchType.LAZY)
    @JoinColumn(name = "userId")
    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }

JPQL code

EntityManagerFactory emfactory = Persistence.createEntityManagerFactory("JPA_TEST");
        EntityManager entitymanager = emfactory.createEntityManager();
        String jpql2 = "select uph from UserPasswordHistory uph where uph.user.userId = :userid";
        Query query2 = entitymanager.createQuery(jpql2);
        query2.setParameter("userid", 1305);
        List<UserPasswordHistory> uphList = query2.getResultList();

        for (UserPasswordHistory uph:uphList ) {

            System.out.println(uph.getHistoryId() + " " + uph.getPassword());

        }

Refer to the result from the log file, it will still query the User table which is bold

This is the unexpected query:
