Emmanuel Bernard resolved ANN-541:
----------------------------------
Resolution: Cannot Reproduce
Assign To: Emmanuel Bernard
Works for me, check org.hibernate.test.annotations.xml.hbm.HbmTest.testManyToOneAndInterface()
I managed to reproduce yo error when the package names in the hbm files where wrong.

> 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:
