JPA OneToOne(optional=true) not supported, supported alternative NotFound() is hibernate-proprietary! ----------------------------------------------------------------------------------------------------- Key: HHH-4982 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4982 Project: Hibernate Core Issue Type: Bug Environment: Hibernate 3.3.1, annotations 3.4.0, MsSQL DB. Reporter: Bruno Melloni Rejected issue ANN-725 covers this partially. I might have misunderstood, but it seems the reason for rejecting is that @NotFound provides the same capability. All information I could find for JPA and other ORM tools indicates that this capability is supplied by @OneToOne(optional=true). Hibernate seems to be the lone ORM tool that requires the use of a proprietary annotation: @NotFound. @NotFound works, but the problem is that it makes the application no longer be pure-JPA. Not supporting pure-JPA outer joins would seem to be a major bug.
