NPE at org.apache.openjpa.jdbc.meta.MappingInfo.mergeJoinColumn(MappingInfo.java:1400)
---------------------------------------------------------------------------------------

Key: OPENJPA-1141
URL: https://issues.apache.org/jira/browse/OPENJPA-1141
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 1.2.0
Reporter: Yann
Fix For: 1.2.2
Attachments: TestMappingProblem.zip

We have the NPE shown below in a reproducible testcase (ZIP attached to JIRA ...).

We've reduced our complex intended target domain model (about 200+ Entities) to a simpler model with only 3 classes which illustrate the problem: You'll find attached a test project with a first entity which has a a OneToMany (with an ElementJoinColumns, but that shouldn't matter?) to a second entity has a ManyToOne to a third entity. The middle entity has a Composite ID Class including a ManyToOne as a key, which according to http://openjpa.apache.org/builds/1.2.0/apache-openjpa-1.2.0/docs/manual/ref_guide_pc_oid.html#ref_guide_pc_oid_entitypk is supported, so this seems a bug in OpenJPA's mapping algos, somehow?

Michael Dick commented on OPENJPA-1141:
---------------------------------------

The entities contain comments indicating that they were generated. Did you use the OpenJPA ReverseMappingTool, or something else (ie Dali)?

If you used the OpenJPAReverseMappingTool then would it be possible to see the table ddl that resulted in these entities? It looks like some annotations need to be added to complete the mappings.

Martin Dirichs commented on OPENJPA-1141:
-----------------------------------------

There seems to be no problem with the mapping of the supplied testcase as such. The reported exception is caused while OpenJPA resolves the primary key fields of NotepadEntity. Since one of the primary key fields of NotepadEntity is the id of another entity, namely TypeEntity, the primary key fields of NotepadEntity may only be completely resolved after TypeEntity has been resolved. However, the mapping data resolution algorithm of OpenJPA doesn't take into account this type of dependency between entities.

See org.apache.openjpa.jdbc.meta.ClassMapping, methods resolveNonRelationMappings() and resolveMapping(). Inside the latter, there already seems to be a workaround for this deficiency of OpenJPAs resolution strategy. Here is says in line 838 (I'm referencing to the 2.0.0-M2 source):
// set resolve mode to force this field mapping to be
// resolved again. The need to resolve again occurs when
// a primary key is a relation field with the foreign key
// annotation. In this situation, this primary key field
// mapping is resolved during the call to
// resolveNonRelationMapping. Since it is a relation
// field, the foreign key will be constructed. However,
// the primary key of the parent entity may not have been
// resolved yet, resulting in missing information in the fk

Unfortunately, there are situations such as in the reported test case that cause an exception before the code following the above comment runs. A more promising strategy would be to resolve the entities in the correct order taking into account the dependencies of their primary key fields. Then this workaround would not be needed at all and the reported exception would no longer happen.

Of course, the code responsible for determining the correct order of entity resolution would have to deal with cycles, which may occur as the result of incorrect mappings. However, I can't think of any situation where cyclic references of primary key fields between entities would make any sense, so this case can probably reported as an error and remain unhandled.

Oh, btw. I would be glad to help testing any fix for this.

Michael Vorburger commented on OPENJPA-1141:
--------------------------------------------

Michael Dick, in response to your questions (as also via IBM PMR 44438 500 624) :

Attached a ddl.sql which represents the three physical tables that PortfolioEntity, NotepadEntity & TypeEntity need to map to. This is a simplified subset of a more complex existing (non changeable) real-world target DDL schema. Note that the defect (NPE) occurs inside OpenJPA within jdbc.meta.MappingInfo BEFORE any SQL at all is actually executed - this DDL is FYI as requested, but the initially provided test case actually fails with NPE and demonstrates the problem WITHOUT any DB / DDL. See Martin Dirichs comments above.

Regarding the comment in the .java that says "This file has been automatically generated, DO NOT MODIFY!", please ignore that - strictly speaking all those *Entity classes (not just Notepad) were generated from some kind of in-house meta description, but NOT by the OpenJPAReverseMapping tool, but by a proprietary code gen. tool. That should be irrelevant for the purposes of this discussion though, please just assume for this discussion that it was hand-written, i.e. the generator could be adapted by us if there is a solution in adding any annotations as you suggest - but which?

Michael Dick commented on OPENJPA-1141:
---------------------------------------

Hi Michael,

I haven't taken a look at this issue since I made the earlier remarks, I'll take another look this morning and get back to you. Martin's comments above are intriguing though - at first glance I thought it was an incomplete mapping issue, but now I'm not sure.

Thanks for the explanation of how the entities get generated, too by the way.

B.J. Reed commented on OPENJPA-1141:
------------------------------------

One thing I tried was playing around with the entities and persisting them before creating/running the query.

Looks like persisting a TypeEntity (even one that's not used) seems to tweak the algorithm enough to get around the NullPointerException.

I changed the doTest method to do the following:

public void testIt () throws Exception {
EntityManager em = emf.createEntityManager();

em.getTransaction().begin();
TypeEntity te = new TypeEntity();
em.persist(te);

Query query = em.createQuery("SELECT o from Portfolio o");
query.getResultList();
em.getTransaction().commit();
em.close();

}

B.J. Reed reassigned OPENJPA-1141:
----------------------------------

Assignee: (was: B.J. Reed)

Can someone else take a look at this? I had only agreed originally to look at the work around and have not had much of a chance to try to actually fix the problem. By having it assigned to me, I'm afraid that someone more capable may be kept from looking into this.

> We've reduced our complex intended target domain model (about 200+ Entities) to a simpler model with only 3 classes which illustrate the problem: You'll find attached a test project with a first entity which has a a OneToMany (with an ElementJoinColumns, but that shouldn't matter?) to a second entity has a ManyToOne to a third entity. The middle entity has a Composite ID Class including a ManyToOne as a key, which according to http://openjpa.apache.org/builds/1.2.0/apache-openjpa-1.2.0/docs/manual/ref_guide_pc_oid.html#ref_guide_pc_oid_entitypk is supported, so this seems a bug in OpenJPA's mapping algos, somehow?
