[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=44620#comment-44620 ] 

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

Why do you require a spec for an issue that's supposed to work by common sense? Just ignore the JPA part in the description then. It kinda breaks common sense compatibility.

BTW I didn't attach a pull request. I meant it doesn't make much sense to further defer fixing this bug just because some JPA spec statement is missing. The JPA spec itself isn't perfect, but not persisting the discriminator value is even more pointless than just doing nothing.

> According to

> @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.
