---------------------------------------
Attachment: OPENJPA-2361.zip
> BuildSchema/DDL : removing constraints unique/nullable has no effect.
> ---------------------------------------------------------------------
>
> Key: OPENJPA-2361
> URL: https://issues.apache.org/jira/browse/OPENJPA-2361
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.2.0, 2.2.1
> Environment: Windows 7 64 bits, JRE 1.6.0_43, Derby 10.8.2.2
> Reporter: Guillaume Chauvet
> Attachments: OPENJPA-2361.zip
>
>
> We have noticed during the database upgrade by OpenJPA that an annotated
> field with @Column(unique=true) in our previous DB model - annotated now
> @Column(unique=false) - doesn't remove the old unique constraint. There is
> the same behaviour with @Column(nullable=true/false).
> Current workaround: we drop the constraint with a native SQL request.
> Attached please find two bundled unitary testsuites that reproduce the
> problem.
