> Originally reported in user group message [1] by Frank Schwarz 
> If
> a) Entities A and B that are related in a one-to-many and many-to-one bi-directional
relation (typical Parent-Child pattern)
> b) mapped using a JoinTable instead of conventional mappedBy 
> then
> update/delete operation fails with OptimisticException (which itself is a catch-all and
sometimes misleading). 
> Typical mapping that encounters this error:
> public class Person {
> 	@Id
> 	private long ssn;
> 	
> 	@OneToMany(cascade=CascadeType.ALL)
> 	@JoinTable(name="J_PERSON_ADDRESSES",
> 			joinColumns               = @JoinColumn(name="PERSON_SSN",    referencedColumnName="SSN"),
> 			inverseJoinColumns = @JoinColumn(name="ADDRESS_PHONE", referencedColumnName="PHONE"))
>     private Set<Address> addresses = new HashSet<Address>();
> public class Address {
>    @Id
>    private String phone;
> 	
>     @ManyToOne
>     @JoinColumn(table="J_PERSON_ADDRESSES", referencedColumnName="SSN")
>     private Person person;
