Hibernate complains about an unknown mappedBy property when mapping a bidirectional OneToOne relation with a derived identifier

Description

I have a OneToOne mapping between Foo and Bar where Bar uses a derived identifier. So Bar is the "dependent" entity and has a single primary key attribute which is mapped by the relationship attribute (i.e. using `Id` on the `OneToOne` relationship).

Foo is mapped like this:

and Bar:

This mapping is described in the section 2.4.1.2 of the JPA 2.0 specification, Example 4, case (a) and works with the RI (run mvn test -Peclipselink,h2 on the attached project).

However, Hibernate fails to initialize and complains about the mappedBy attribute:

Run mvn test to reproduce.

Environment

Hibernate 3.5+, any database.

Thanks, Emmanuel.

I've added the attached test as a "FailureExpected test that reproduces this issue:
org.hibernate.test.annotations.derivedidentities.bidirectional.OneToOneWithDerivedIdentityTest

The test has been added to hibernate-core master and 3.6.

Yawn... Is no one able to fix this, has this been fixed already, or is no one interested in fixing this?

Just debugged my app deep into Hibernate's mapper. Not my case. Though, given property somestuff and method getSomeStuff() if I annotate methods as latest guidelines advice I need to write maddedBy="someStuff" not "somestuff" whatever name my entity class property has in case-sensitive point.
