Hibernate version: 3.2.5

Mapping documents: JPA Annotations

Code between sessionFactory.openSession() and session.close():
It's JPQL based unit test (used hibernate as JPA implementation).
This query was executed fine:

Query q = getEntityManager().createQuery(
"SELECT this_.aaId, " +
"this_.patient.lastNamePersistent " +
// ", " +
// "this_.patient.firstNamePersistent " +
"FROM RVOrder this_ " +
"WHERE " +
"this_.aaId IN " +
"( SELECT _1.order.aaId FROM Specimen _1 WHERE _1.aaId IN " +
"( SELECT _2.specimen.aaId FROM SpecimenBarcode _2 WHERE _2.barcode='a')))"
);
List list = q.getResultList();

but this fails during execution:

Query q = getEntityManager().createQuery(
"SELECT this_.aaId, " +
"this_.patient.lastNamePersistent " +
", " +
"this_.patient.firstNamePersistent " +
"FROM RVOrder this_ " +
"WHERE " +
"this_.aaId IN " +
"( SELECT _1.order.aaId FROM Specimen _1 WHERE _1.aaId IN " +
"( SELECT _2.specimen.aaId FROM SpecimenBarcode _2 WHERE _2.barcode='a')))"
);
List list = q.getResultList();

My notes:
Hello!
I need to know is described problem a known bug ? And are there workarounds here, if such exists?

If mappings are needed, I'll attach them. They are quite huge.
Key parts of mapping:

@Entity @Table
class RVOrder {
...
...
...

@OneToMany(mappedBy = "order", cascade = CascadeType.ALL)
public Set<Specimen> getSpecimens()
{
return specimens;
}

}

@Entity @Table
class Specimen {
...
...
...
@ManyToOne
@JoinColumn(name = "RVORDER")
public RVOrder getOrder()
{
return order;
}

@OneToMany(mappedBy = "specimen", cascade = CascadeType.ALL)
public Set<SpecimenBarcode> getBarcodes()
{
return barcodes;
}

}

@Entity @Table
class SpecimenBarcode{
...
...
...
@ManyToOne()
@JoinColumn(name = "SPECIMENREF")
public Specimen getSpecimen()
{
return specimen;
}

}

I've decreased an amount of selected data:

Works fine:

Query q = getEntityManager().createQuery(
"SELECT this_.aaId, " +
"this_.patient.lastNamePersistent " +
", " +
"this_.patient.firstNamePersistent " +
"FROM RVOrder this_ "
);
List list = q.getResultList();

But when add next WHERE clause (which contains subselect from Specimen table). The same NullPointerException appears:

Query q = getEntityManager().createQuery(
"SELECT this_.aaId, " +
"this_.patient.lastNamePersistent " +
", " +
"this_.patient.firstNamePersistent " +
"FROM RVOrder this_ "
+ "WHERE " +
"this_.aaId IN " +
"( SELECT spec1.order.aaId FROM Specimen spec1 WHERE spec1.specimenSource='a')"
);
List list = q.getResultList();
