[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-4720) Improve javax.persistence.metamodel.Attribute support

Improve javax.persistence.metamodel.Attribute support ----------------------------------------------------- Key: HHH-4720 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4720 Project: Hibernate Core Issue Type: Bug Components: entity-manager, metamodel Affects Versions: 3.5.0-Beta-2 Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.5 Time Spent: 2 days, 6 hours, 56 minutes Remaining Estimate: 0 minutes 1) o.h.ejb.metamodel.AttributeFactory is currently using Type.getReturnedClass() from the o.h.type.Type associated with the attibute as it's javaType. That is not accurate in all cases, especially in subclassing scenarios like java.util.Date and the java.sql variants. We should instead look at the Member for the attribute to determine the java type (perhaps applying some validation of the "assignability"). 2) Emmanuel has said there are a few cases where there is a discrepancy between how Hibernate captures information versus how the JPA metamodel package expects to report it. E.g. @ManyToOne @JoinTable where the AnnotationBinder hands this to core as a many-to-many but JPA metadata still expects @ManyToOne to be reported.
