      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();
