 <div class="block">Used to override a mapping for an entity relationship.

  <p> May be applied to an entity that extends a mapped superclass to
  override a relationship mapping defined by the mapped
  superclass. If not specified, the association is mapped the same as
  in the original mapping. When used to override a mapping defined by
  a mapped superclass, <code>AssociationOverride</code> is applied to
  the entity class.

  <p> May be used to override a relationship mapping from an
  embeddable within an entity to another entity when the embeddable
  is on the owning side of the relationship. When used to override a
  relationship mapping defined by an embeddable class (including an
  embeddable class embedded within another embeddable class),
  <code>AssociationOverride</code> is applied to the field or
  property containing the embeddable.

  <p> When <code>AssociationOverride</code> is used to override a
  relationship mapping from an embeddable class, the
  <code>name</code> element specifies the referencing relationship
  field or property within the embeddable class. To override mappings
  at multiple levels of embedding, a dot (".") notation syntax must
  be used in the <code>name</code> element to indicate an attribute
  within an embedded attribute.  The value of each identifier used
  with the dot notation is the name of the respective embedded field
  or property.

  <p> When <code>AssociationOverride</code> is applied to override
  the mappings of an embeddable class used as a map value,
  "<code>value.</code>" must be used to prefix the name of the
  attribute within the embeddable class that is being overridden in
  order to specify it as part of the map value.

  <p> If the relationship mapping is a foreign key mapping, the
  <code>joinColumns</code> element is used.  If the relationship
  mapping uses a join table, the <code>joinTable</code> element must
  be specified to override the mapping of the join table and/or its
  join columns.

  <pre>
     Example 1: Overriding the mapping of a relationship defined by a mapped superclass

     &#064;MappedSuperclass
     public class Employee {
         ...
         &#064;ManyToOne
         protected Address address;
         ...
     }

     &#064;Entity
         &#064;AssociationOverride(name="address",
                              joinColumns=&#064;JoinColumn(name="ADDR_ID"))
         // address field mapping overridden to ADDR_ID foreign key
     public class PartTimeEmployee extends Employee {
         ...
     }
  </pre>

  <pre>
     Example 2: Overriding the mapping for phoneNumbers defined in the ContactInfo class

     &#064;Entity
     public class Employee {
         &#064;Id int id;
         &#064;AssociationOverride(
           name="phoneNumbers",
           joinTable=&#064;JoinTable(
              name="EMPPHONES",
              joinColumns=&#064;JoinColumn(name="EMP"),
              inverseJoinColumns=&#064;JoinColumn(name="PHONE")
           )
         )
         &#064;Embedded ContactInfo contactInfo;
        ...
     }

     &#064;Embeddable
     public class ContactInfo {
         &#064;ManyToOne Address address; // Unidirectional
         &#064;ManyToMany(targetEntity=PhoneNumber.class) List phoneNumbers;

     &#064;Entity
     public class PhoneNumber {
