more responsive forum than this ;)

I saw ReferenceTest test worked with OJB 1.0.1 too, with a different 
mapping of the interface. Did you tried to declare the 
reference-descriptor and fk-field in the interface class mapping too?

e.g.
Class RefObject is an interface
<class-descriptor class="org.apache.ojb.broker.ReferenceTest$RefObject">
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjA"/>
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjB"/>
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjC"/>

        <field-descriptor
             name="fkId"
             column="FK_REF"
             primarykey="false"
             jdbc-type="INTEGER"
            access="anonymous"
        />
        <reference-descriptor
            name="ref"
            class-ref="org.apache.ojb.broker.ReferenceTest$RefObject"
            proxy="false"
            auto-retrieve="true"
            auto-update="true"
            auto-delete="false">
                <foreignkey field-ref="fkId"/>
        </reference-descriptor>
    </class-descriptor>
If this doesn't work, try the mapping mentioned by Tom.

Armin
