I am following the A to B relationship (many to one) where B is abstract and
the relationship lazy, I get a ClassCastException:

com.mycompany.myproject.MyEntityB_$$_javassist_1.getMyEntityB1(EntiteB_$$_javassist_1.java)
| at
com.mycompany.myproject.MyServiceImpl.getMyEntityB1FromA(MyServiceImpl.java:68)

I tried to replace Javassist by CGLib but I got the same:

com.mycompany.myproject.MyServiceImpl.getMyEntityB1FromA(MyServiceImpl.java:68)

Here are my entities:
@Entity
| public class MyEntityA {
| @Id
| private int id;
| private String name;
| @ManyToOne(fetch=FetchType.LAZY)
| private MyEntityB myEntityB;
| ...
| }
| @Entity
| @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
| public abstract class MyEntityB {
| @Id
| private int id;
| private String name;
| @OneToMany(mappedBy="MyEntityB")
| private List<MyEntityA> myEntitiesA=new ArrayList<MyEntityA>();
| ...
| }
| @Entity
| public class MyEntityB1 extends MyEntityB {
| @OneToMany(mappedBy="myEntityB1")
| private List<MyEntityB2> myEntitiesB2=new ArrayList<MyEntityB2>();
| ...
| }
| @Entity
| public class MyEntityB2 extends MyEntityB {
| @ManyToOne
| private MyEntityB1 myEntityB1;
| ...
| }
|
Can you tell me where I am wrong?
