----------------------------
Attempting to provide better test cases I found out new info about this bug.
1 - using JTA (hiberjta.zip) a NPE is thrown when em.createQuery().getResultList() method
is invoked (select test);
2 - using JTA a StackOverflowException is thrown when em.find() method is invoked (find
test);
3 - using RESOURCE_LOCAL (hiberlocal.zip) no errors are thrown if only select test or find
test is executed;
4 - using RESOURCE_LOCAL an exception in thrown if both select test and find test are
executed together. The type of error (NPE or SOE) depends on which method is executed
before (Junit does not guarantee the execution order);

Alfio commented on HHH-6813:
----------------------------
I tried to debug hiberjta test to help you to solve this problem. I compared @Id @OneToOne
tecnique with @MapsId one.
The NPE is thrown in AbstractEntityPersister.loadByUniqueKey() because uniqueKeyLoaders
map is empty. In the @MapsId case there is one uniqueKeyLoader bound to person property
(wich has the @MapsId annotation).
(PS: If I set useStaticLoader to false the test passes, but I don't think this is a
solution.)
A uniqueKeyLoader is created scanning properties in entityMetamodel. This happens in
AbstractEntityPersister.createUniqueKeyLoader() method. What I noticed is that properties
do not include identifier, hence no uniqueKeyLoader can be created for id in @Id @OneToOne
case.
I think should be added a routine to add uniqueKeyLoader in the case of @Id @OneToOne. To
do so the needed information could be extracted from
entityMetamodel.getIdentifierProperty() but in @Id @OneToOne case identifierProperty is
not set properly. For example entityMetamodel.getIdentifierProperty().getName() returns
null intead of "id".
In PropertyBinder.bind() the control enters in 'if ( isXToMany ||
entityBinder.wrapIdsInEmbeddedComponents() ) {}' block only in @Id @OneToOne case.
There are two FIXME, the problem may be here.
I hope my efforts are usefull.

----------------------------
Do you think you can fix this issue in the next release?
@Id @OneToOne cause NullPointerException during query
-----------------------------------------------------
Key: HHH-6813
URL: https://hibernate.onjira.com/browse/HHH-6813
Project: Hibernate ORM
Issue Type: Bug
Components: core, entity-manager
Affects Versions: 3.6.8, 4.0.0.CR5
Environment: Hibernate 4.0.0.CR5, PostgreSQL 9.1.1, Glassfish 3.1.1
Reporter: Alfio
Labels: jpa2
Attachments: hiberjta.zip, hiberlocal.zip, hibertest.war, hibertest.zip
I've two entities, Person and PersonInfo, with a one-to-one relation:
{code:title=Person.java}
@Entity
public class Person {
@Id
private Integer id;
@Basic
private String name;
@OneToOne( mappedBy = "id" )
private PersonInfo personInfo;
...getters&setters...
}
{code}
{code:title=PersonInfo.java}
@Entity
public class PersonInfo {
@Id
@OneToOne
private Person id;
@Basic
private String info;
...getters&setters...
}
{code}
Hibernate correctly creates two tables but a NPE occours during a simple select query
(only if tables have one or more records)
em.createQuery("SELECT p FROM Person p").getResultList();
...
java.lang.NullPointerException

-------------------------------
Please, fix it! It's very critical bug - essential JPA-functionality.
