Description

Given the following entity definitions:

@Entity
@IdClass(PersonId.class)
public class MedicalHistory implements Serializable {

private static final long serialVersionUID = 1L;
@Id
@OneToOne
private Person patient;
private String doctorName;
.....

-------------------------------
@Entity
@IdClass(PersonId.class)
public class Person implements Serializable {

@Id
String firstName;
@Id
String lastName;
String ssn;
...
-------------------------------
public class PersonId implements java.io.Serializable {

String firstName;
String lastName;

-------------------------------
Removing MedicalHistory as shown below throws ClassCastException:

MedicalHistory newMHistory = em.find(MedicalHistory.class, personId);
em.remove(newMHistory);
et.commit();
