Defining multiple Address properties in Person per AddressType by a triple join table

I've here a database with a PERSON - ADDRESS - ADDRESS_TYPE relationship maintained by a triple join table PERSON_ADDRESS. The PERSON-ADDRESS relationship is effectively one-to-many.

PERSON

ID FIRSTNAME LASTNAME
-- --------- --------
1  John      Doe
2  Jane      Doe

ADDRESS

ID STREET               CITY
-- -------------------- -------------
1  Home Street 1        Hometown
2  Office Street 1      Officetown
3  Main Street 1        Maintown
4  Business Building 1  Businesstown

ADDRESS_TYPE

ID NAME
-- ---------------
1  Home Address
2  Office Address

PERSON_ADDRESS

PERSON_ID ADDRESS_TYPE_ID ADDRESS_ID
--------- --------------- ----------
1         1               1
1         2               2
2         1               3
2         2               4

For practical reasons, I'd like to have my Person entity to end up like:

public class Person {
    private Address homeAddress; // Insertable/updateable by ADDRESS_TYPE_ID=1
    private Address officeAddress; // Insertable/updateable by ADDRESS_TYPE_ID=2
}

Is this ever possible with JPA 2.0 annotations?

I've read the Map Key Columns chapter of the JPA wikibook and it seems that I have to use a @MapKeyJoinColumn, but it's not entirely clear to me how to successfully use it in this situation. I expected to see a @JoinColumn example along it, but it is absent in the code snippets in the wikibook.

If that's not possible with @MapKeyJoinColumn, then an alternative approach with help of maybe @MapKeyClass on a Map<AddressType, Address> is also welcome, as long as I can end up with a getHomeAddress() and getOfficeAddress() in the Person entity.
