Jira issue originally created by user mac_nibblet:

If you have a embeddable on a mapped superclass you get the following error

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping>
    <embeddable name="DealFinder\Core\ValueObject\Coordinates">
        <field name="latitude"  type="float" precision="10" scale="6" nullable="true"/>
        <field name="longitude" type="float" precision="10" scale="6" nullable="true"/>
    </embeddable>
</doctrine-mapping>

Doctrine\ORM\Mapping\MappingException: Duplicate definition of column 'coordinates_latitude' on entity 'DealFinder\Location\Entity\LocationEntity' in a field or discriminator column mapping.

Moving it to the entity mapping resolves the issues but gives you duplicated code.
