Nicolas De Cubber commented on HHH-1797:
----------------------------------------

The solution is to move the <set> outside the <join>, like this :

<subclass name="LicensePlateSuspend" discriminator-value="license plate suspend">
            <set name="licensePlates">
                <key>
                    <column name="licensePlateSuspendId"/>
                    <column name="licensePlate"/>
                </key>
                <one-to-many class="LicensePlate"/>
            </set>
            <join table="LicensePlateSuspend">
                <key column="licensePlateSuspendId"/>
            </join>
        </subclass>
