Bug Mixing Annotations with Mapping Files. (Minimal Test Case Attached)
-----------------------------------------------------------------------
Key: ANN-541
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-541
Project: Hibernate Annotations
Type: Bug
Environment: Hibernate Annotations 3.2.1.GA
Hibernate 3.2.1
Reporter: Adam T
Attachments: HibernateMixedMappingsTestCase.zip
I have found a bug in Hibernate when mixing annotations and mapping files. I have
generated a minimal test case. Additionally, I have confirmed that the error does not
appear when all classes use annotations.
There are two mapped classes AImpl and BImpl. AImpl extends BImpl. A third annotated class
ZImpl, refers to BImpl through a ManyToOne relationship. All method signatures refer to
these classes by their interfaces A, B, and Z; however, Hibernate is instructed to use the
*Impl classes when necessary.
I am NOT mixing annotations and mappings in a single inheritance hierarchy. All classes
implement Serializable by extending their Serializable interfaces.
The minimal test case is attached as a zip and included below:

When the AImpl and BImpl classes are annotated, the error disappears.

private Integer aId = 0;
public AImpl() {
}
@Id
@Column(name = "aID")
public Integer getAId() {
return this.aId;
}
public void setAId(Integer aId) {
this.aId = aId;
}
}
BImpl.java:
package test;
import javax.persistence.Entity;
import javax.persistence.Table;
@Entity
@org.hibernate.annotations.Proxy(proxyClass = B.class)
@Table(name = "B")
public class BImpl extends AImpl implements B {
private static final long serialVersionUID = 1L;
private Integer bId = 0;
public BImpl() {
super();
}
public Integer getBId() {
return bId;
}
public void setBId(Integer bId) {
this.bId = bId;
}
}
That's all folks!
