Strong Liu, I might need a bit of help after all.

In ProductDetails, change

    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.ALL})
    @JoinColumns({ @JoinColumn(name = "id_product", referencedColumnName = "id_product", nullable = false),
            @JoinColumn(name = "id_product_version", referencedColumnName = "id_product_version", nullable = false) })
    private Product product;

to

    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.ALL})
    @JoinColumn(name = "id_product_version", referencedColumnName = "id_product_version", nullable = false)
    private Product product;

, the "id_product_version" logical name is bound for the product table first, then product_details (as it should be).

The FkSecondPass correctly has both Columns if the @JoinColumns is left in place. So, I believe that's bound correctly.

I'm having trouble understanding if the problem is in:

• Configuration#processFkSecondPassInOrder (as you mentioned, sp.isInPrimaryKey is false for all these cases)
• ToOneFkSecondPass#doSecondPass -> BinderHelper#createSyntheticPropertyReference -> Ejb3JoinColumn#checkReferencedColumnsType()
• The order in which FkSecondPasses are created
