Cascade=CascadeType.ALL not working

Question

Hi. I am using jpa and oracle database. My code is as follows:
SQL
CREATE TABLE rbv.address ( addressId number(11) NOT NULL primary key, postcode varchar2(100));
CREATE TABLE rbv.person ( personId number(11) NOT NULL primary key, name varchar2(100), addressId number(11) NOT NULL REFERENCES rbv.address);
Persistence
Set<Person> persons = new HashSet<Person>();     for (String name :personRequest.getName()){     Person person = new Person(name);     persons.add(person);     }     Address address = new Address(addressRequest.getPostcode(),persons);     em.persist(address);
Address.java
package com.ao.persistenceservice.domainobjects; import java.util.HashSet; import java.util.Set; import javax.persistence.CascadeType; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.OneToMany; import javax.persistence.SequenceGenerator; import javax.persistence.Table; /** * Address generated by hbm2java */ @Entity @Table(name="rbv.ADDRESS" ) public class Address  implements java.io.Serializable {     private long addressid;     private String postcode;     private Set<Person> persons = new HashSet<Person>(0);     public Address() {     }     public Address(String postcode,Set<Person> persons) {       this.postcode = postcode;     }       @Id     @GeneratedValue(generator = "AddressSeq",             strategy = GenerationType.SEQUENCE)             @SequenceGenerator(name = "AddressSeq",                                 sequenceName = "seq_address_id",                                 allocationSize = 1)     @Column(name="ADDRESSID", unique=true, nullable=false, precision=11, scale=0)     public long getAddressid() {         return this.addressid;     }         public void setAddressid(long addressid) {         this.addressid = addressid;     }         @Column(name="POSTCODE", length=100)     public String getPostcode() {         return this.postcode;     }         public void setPostcode(String postcode) {         this.postcode = postcode;     } // cascade indicates that when we persist, remove, refresh or merge this // entity all the entities held in this field would be persist, remove, // delete or update. @OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL) @JoinColumn(name="ADDRESSID")     public Set<Person> getPersons() {         return this.persons;     }         public void setPersons(Set<Person> persons) {         this.persons = persons;     } }
Person.java
package com.ao.persistenceservice.domainobjects; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import javax.persistence.SequenceGenerator; import javax.persistence.Table; /** * Person generated by hbm2java */ @Entity @Table(name="rbv.PERSON" ) public class Person  implements java.io.Serializable {     // Fields        private long personid;     private String name;     // Constructors     /** default constructor */     public Person() {     }         /** full constructor */     public Person(String name) {       this.name = name;     }       // Property accessors     @Id     @GeneratedValue(generator = "PersonSeq",             strategy = GenerationType.SEQUENCE)             @SequenceGenerator(name = "PersonSeq",                                 sequenceName = "seq_person_id",                                 allocationSize = 1)     @Column(name="PERSONID", unique=true, nullable=false, insertable=true, updatable=true, precision=11, scale=0)     public long getPersonid() {         return this.personid;     }         public void setPersonid(long personid) {         this.personid = personid;     }         @Column(name="NAME", unique=false, nullable=true, insertable=true, updatable=true, length=100)     public String getName() {         return this.name;     }         public void setName(String name) {         this.name = name;     } }
Only my address table is being populated. In debug mode I have made sure the person objects are present.

Thank you! You saved my life. After removing @MappedSuperClass, all is well.
The entity manager is now saving my CreditCardPaymentMethod objects as CreditCardPaymentMethod classes instead of AbstractPaymentMethod classes.
