When redefining the name of an @Embeddable field, it's name is not prefixed with the name of the embedding field any more.

E.g. in EmbeddableMappingTest the field "zipCode" of the embeddable Address gets a specific column name. This results in that field being pulled to the top level in the persisted mapping:

{
    'homeAddress' : {
        'country' : 'France',
	...
    },
    'postal_code' : '75007',
    ...
"}"

Whereas I think it still should be located under the "homeAddress" node:

{
    'homeAddress' : {
        'country' : 'France',
        'postal_code' : '75007',
	...
    },
    ...
}
