The attached software will create the following output which proofs that the created AmountManufactured contains a non-NULL reference to Part, but after find() it registers an instance where that reference IS NULL: "Register the existing object entities.ManufacturedAmount@11e9c82e(pk=(part='null, 'year='1900'))". When using @Cacheable(false) at AmountManufactured this does not happen, as it does not register an existing (obviously broken) instance then but loads all data (incl. reference to Part) from the database. So it seems the problem is that multiply mapped fields do not get updated correctly in the cache.

Complete Eclipse project demonstrating the bug
This ZIP file contains a complete Eclipse project demonstrating the bug. It contains all source code including the used entities and persistence.xml files.
This bug is a showstopper for GlassFish v3.1.1_b11 as http://java.net/jira/browse/GLASSFISH-17036 bug is dependent of this problem. When you say "failure-free EARs" what does that mean? I am trying to triage this issue, but cannot run the recreation because I do not have data in my local database. I also do not have an IAnywhere JDBC driver (in case the data in the initial test case is publicly available) (In reply to comment #4) > When you say "failure-free EARs" what does that mean? I mean that EclipseLink does not complaint about bugs in this persistence unit configuration at deployment or runtime (as it would do e. g. when there are typos in column names etc.). (In reply to comment #5) > I am trying to triage this issue, but cannot run the recreation because I do > not have data in my local database. > > I also do not have an IAnywhere JDBC driver (in case the data in the initial > test case is publicly available) The only thing you need is one row in the Part table that has the primary key of id_teil="D-0077" and id_teileversion="1". No other existing data is needed. IAnywhere is not needed as this is not specific to that particular database (I assume), so you can just replace driver and url entries in persistence.xml to run it with any other database. In case it will work (and you assume that it is IAnywhere related) I can send you a download link for an unlimited free developer's licence of that and provide a ready-to-use database including the above data. To elaborate on the workarounds. There are 2. 1. Make both entities cacheable 2. Make both entities non-cacheable Setting initial target to 2.3.1 - although I do not agree this is a showstopper, we should do our best to address this by 2.3.1.
The recreation needs code similar to the following close the the beginning of the main method to populate the data
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
Part part1 = new Part();
PartPrimaryKey pk = new PartPrimaryKey();
pk.setId("D-0077");
pk.setVersion("1");
part1.setPrimaryKey(pk);
em.persist(part1);
tx.commit();
em.clear();
JpaHelper.getServerSession(emf).getIdentityMapAccessor().initializeAllIdentityMaps();
The issue occur because of the relationship between cacheable and non-cacheable entities.
The code in question is the combination of this code in UnitOfWork.registerExistingObject
if (registeredObject == null) {
// This is a case where the object is not in the session cache,
// so a new cache-key is used as there is no original to use for locking.
// It read time must be set to avoid it being invalidated.
CacheKey cacheKey = new CacheKey(primaryKey);
cacheKey.setReadTime(System.currentTimeMillis());
cacheKey.setIsolated(true); // if the cache does not have a version then this must be built from the supplied version
registeredObject = cloneAndRegisterObject(objectToRegister, cacheKey, descriptor);
}
And this code in ForeirnReferenceMapping.buildClone
if (!this.isCacheable && (cacheKey != null && !cacheKey.isIsolated())){
ReadObjectQuery query = new ReadObjectQuery(descriptor.getJavaClass());
query.setSession(cloningSession);
attributeValue = valueFromRow(cacheKey.getProtectedForeignKeys(), null, query, cacheKey, cloningSession, true, null);
}
Notice, the cache key we build is set to isolated and the condition on the if statement prevents us from using protecteForeignKeys if the cache key is isolated
(In reply to comment #8) > To elaborate on the workarounds. There are 2. > > 1. Make both entities cacheable > 2. Make both entities non-cacheable Tom, thanks for this, but we already know that. The problem is that this is not an acceptable workaround as it enforces a change of the EAR. But see, the vendor of the EAR is an ISV so he (= we) will not switch off a WORA EAR just to run correct in GlassFish, while the same source change is not needed to run in any other application server (here: other JPA prodivers). The only accepted solution is to fix it, and the only accepted workaround is one that does not break WORA of the packaged EAR product (i. e. for example, changing some options at the GlassFish administration console at deployment or later). (In reply to comment #9) > Setting initial target to 2.3.1 - although I do not agree this is a > showstopper, we should do our best to address this by 2.3.1. As I explained above, as an ISV we must not change our packaged product (= EAR) just to allow some of our customers to run it on GlassFish (= EclipseLink), while it works unchanged in other servers. This breaks WORA and such is not acceptable. Any solutions available which will not enforce source code changes and such break the WORA principle? Another workaround: Avoid the find call, do the following instead:
final ManufacturedAmount amount = (ManufacturedAmount)em.createQuery("select m from ManufacturedAmount m where m.pk.year = :year and m.pk.partId = :id and m.pk.partVersion = :version").setParameter("year", YEAR).setParameter("id", part.getId()).setParameter("version", part.getVersion()).getResultList().get(0);

proposed fix
Fix checked in to trunk and 2.3.1 The fix makes use of the primary key that is available in a finder to do a cache lookup while we are registering the object. This allows cloning to occur when we know about the protected relationship.

Build Identifier: GFv3.1.1_b11 An entity created via entity manager A having a non-NULL ManyToOne reference contains NULL in that same reference after find() by entity manager B under certain circumstances unless @Cacheable(false) is used. The following code produces this problem (this creates a row in AmountManufactured correctly pointing to a row in Part, but the second EntityManager find()s an AmountManufactured having NULL in the reference to Part): EntityManagerFactory emf = Persistence.createEntityManagerFactory("test"); EntityManager em = emf.createEntityManager(); EntityTransaction tx = em.getTransaction(); tx.begin(); Part part = em.find(Part.class, new PartPrimaryKey(PART_ID, PART_VERSION)); if (part != null) { final ManufacturedAmount manufacturedAmountToSaved = new ManufacturedAmount(part, YEAR); em.persist(manufacturedAmountToSaved); System.out.println("\nAmount saved.\n"); } else { System.out.println("\nPart not found.\n"); tx.rollback(); return; } tx.commit(); em.close(); em = emf.createEntityManager(); tx = em.getTransaction(); tx.begin(); final ManufacturedAmount amount = em.find(ManufacturedAmount.class, new ManufacturedAmountPk(PART_ID, PART_VERSION, YEAR)); if (amount == null) System.out.println("\nAmount = NULL.\n"); else System.out.println(String.format("\n Part = %s\n", amount.getPart() == null ? "NULL" : part.toString())); tx.commit(); This is a showstopper for GlassFish 3.1.1_b11 as it prevents failure-free EARs from running correctly without getting modified (here: without switching off the cache). As such, it should get fixed ASAP. Reproducible: Always Steps to Reproduce: Execute attached code.
