[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4307) Optional one-to-one association with join table cannot exist

[Miroslav Havram (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35924#action_35924 ] 

Miroslav Havram commented on HHH-4307:
--------------------------------------

It had worked in versions 3.5.0-Beta-1 and 3.5.0-Beta-2 because hibernate.check_nullability by default evaluated to false in BeanValidationActivator.
Starting with version 3.5.0-CR-1 and changes in BeanValidationActivator, hibernate.check_nullability now evaluates by default to true - which activates nullability check (class Nullability) which fails in this case.

> In the case of the optional one-to-one association with the join table, it is not possible to have independant instances of entities.
> Entity at the inverse end of the association cannot be persisted without being first linked to the entity on the other (non-inverse) end of the association.
