[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4358) Having to use @ForceDiscriminator kind of breaks JPA compatibility

[Karsten Wutzke (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=44626#comment-44626 ] 

Karsten Wutzke commented on HHH-4358:
-------------------------------------

I'm sorry I can't help fixing Hibernate bugs. I'd rather switch back to EclipseLink as soon as support for it is available in AS 7.

A config option as described would at least be a viable workaround for new projects. I understand your point about existing apps, but it still doesn't make sense to me not to persist the discriminators. I might have to find out about the JPA spec. Stay tuned.

> According to
> http://opensource.atlassian.com/projects/hibernate/browse/ANN-36
> @ForceDiscriminator was created as a quick workaround to a problem.
> Yes, it solves the problem, but it creates a new problem:
> the source code which previously had only JPA annotations, now need to be annotated by a Hibernate annotation,
> causing that the the source code is now unable to use just any JPA provider.
> Major portability issue!
> Everyone who likes Open Source, hates Lock-Ins!
> My proposal: change the default to a more sane force=true, so that @ForceDiscriminator will not be needed for general JPA projects.
> (And create a @DisableDiscriminator Hibernate annotation, for those who like to brake their code).
> If changing default behavior is risky, don't fix this on older versions, but lets change this from 3.5.0-Beta2.
