@Any mapping fails during configuration: "@Any requires an explicit @JoinColumn(s)"
-----------------------------------------------------------------------------------

                 Key: ANN-819
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-819
             Project: Hibernate Annotations
          Issue Type: Bug
    Affects Versions: 3.4.0.GA, 3.4.0.CR2, 3.4.0.CR1, 3.3.1.GA
         Environment: Hibernate core 3.2.4.sp1 (reported in 3.3.1.GA as well)
Hibernate annotations 3.3.1.GA (reported in 3.4.0.GA as well)
Hibernate entity manager 3.3.1.ga
MySQL 5.0.45
            Reporter: Noah Miller


When I try to apply the @Any annotation, I get the following exception:

ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: name=persistence.units:jar=test-build.jar,unitName=blueserve state=Create
org.hibernate.AnnotationException: @Any requires an explicit @JoinColumn(s): com.builderadius.blueserve.model.Note.noteOwner

See the forum posting http://forum.hibernate.org/viewtopic.php?p=2403045 for another description of this problem.  That thread suggests the problem is with EJB3OverridenAnnotationReader not adding properties annotated with @JoinColumn if xml mapping files exist.

My code is:

    @Any(metaColumn = @Column(name = "RelatedRecType"))
    @AnyMetaDef(idType = "integer", metaType = "string", metaValues = {
            @MetaValue(targetEntity = Approval.class, value = "approval"),
            @MetaValue(targetEntity = ZoningPermit.class, value = "zoningpermit") })
    @JoinColumn(name = "RelatedRecNum", nullable = false)
    public BlueserveEntity getNoteOwner()
    {
        return this.noteOwner;
    }

An orm.xml file (auto-generated by seam-gen) exists in this project, though it has no entity mappings and there are no other hbm.xml files.  When I remove this file, I no longer receive the exception (that's not a long-term solution).
