Thanks. I was trying to map the NullRelations testcase from David
Blevins to an existing junit testcase, but realized after I sent the
email that David's testcase is using 3 entities and 2 of them are using
join-columns.

Don,
Good question. A bidirectional one-to-one relationship requires a mappedBy
element, but only on one side of the relationship. Not both. In this
particular case, the mappedBy element indicates that the BidiChild is the
owning entity for this relationship (based on the oneToOneParent
attribute). A general rule is that the mappedBy element is never on both
sides of a relationship.

I would expect the BidiParent/BidiChild entities under -
openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/persistence/relations/
to have a bi-directional mappedBy annotation for the OneToOne relations,
but the child doesn't -
BidiParent -
@OneToOne(fetch=FetchType.LAZY, mappedBy="oneToOneParent")
private BidiChild oneToOneChild;
BidiChild -
@OneToOne(fetch=FetchType.LAZY)
private BidiParent oneToOneParent;
Is this correct?
