I have attached a compressed tar file with some example code of what is not working as expected

BTW I get a this error

My case is from a complex auto-generated model - I will endeavour to provide a small example
This is sort of the converse of https://hibernate.atlassian.net/browse/HHH-7610#icft=HHH-7610 in that I want to be able to model the case where the whole embedded field is nullable even when some of the fields of the embeddable are marked as not nullable - it has been suggested on stackoverflow that using
@AttributeOverride(name="value", column = @Column(name="error_value",nullable = true)with a new column annotation solves this problem, and would be a fine solution, but it does not work in my case (and there is at least one "doesn't work for me" comment on stack overflow too).
