Prent-Child in/with one single Entity/Typ

Hello!

Is it possible to implement loops many-to-one or one-to-many in/with one Type of Entity?

I mean... for example (simply abstract):

Code:

@Entity
@Table(name="atable")
class A {

 @Id
 private id;

 private parent_id;
 
 @Transient
 @ManyToOne(targetEntity=A.class)
 @JoinColumn(name="id", table="atable", referencedColumnName="parent_id")
 private List<A> children;

}

Is something like written above possible?

Thank You in advance.

P.S. there is one but --- i may not change DB-structure. I work in pojo mode (ddl-validation). I may not set FK on parent_id and may not set children-property persistent.
