Jpa元模型属性，不能定义父类继承的属性吗？

怎么解决这个问题？

父类 BaseEntity

import javax.persistence.Column;
import javax.persistence.MappedSuperclass;


import java.io.Serializable;
import java.time.LocalDateTime;

@MappedSuperclass
public abstract class BaseEntity implements Serializable {

	private static final long serialVersionUID = -8506961188930650652L;


	@Column(name = "version", columnDefinition = "INT(11) UNSIGNED COMMENT '版本号'")
	private Integer version;

	@Column(name = "create_date", columnDefinition = "TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间'")
	private LocalDateTime createDate;
}

子类 User

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "user")
@org.hibernate.annotations.Table(appliesTo = "user", comment = "用户表")
public class User extends BaseEntity {
	/**
	 * 
	 */
	private static final long serialVersionUID = 8175166175439387541L;

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Integer id;
	
	@Column(columnDefinition = "varchar(20) COMMENT '昵称'")
	private String name;
	
}

元模型

import java.time.LocalDateTime;

import javax.persistence.metamodel.SingularAttribute;
import javax.persistence.metamodel.StaticMetamodel;

@StaticMetamodel(User.class)
public abstract class User_ {
	public static volatile SingularAttribute<User, Integer> id;
	public static volatile SingularAttribute<User, String> name;
	public static volatile SingularAttribute<User, Integer> version;		   // 父类继承的属性
	public static volatile SingularAttribute<User, LocalDateTime> createDate;  // 父类继承的属性
}

测试

EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("mysql");
CriteriaBuilder criteriaBuilder = entityManagerFactory.getCriteriaBuilder();
EntityManager entityManager = entityManagerFactory.createEntityManager();
EntityTransaction entityTransaction = entityManager.getTransaction();

entityTransaction.begin(); 
try {
	CriteriaQuery<User> criteriaQuery = criteriaBuilder.createQuery(User.class);
	Root<User> root = criteriaQuery.from(User.class);
	Predicate predicate = criteriaBuilder.greaterThan(root.get(User_.createDate), LocalDateTime.now()); // java.lang.NullPointerException
	criteriaQuery.where(predicate);
	entityTransaction.commit();
}catch (Exception e) {
	entityTransaction.rollback();
	throw e;
}finally {
	entityManager.close();
	entityManagerFactory.close();
}
