> Key: OPENJPA-1899

> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.0.0
> Environment: N/A
> Reporter: Robert Krier
> Assignee: Rick Curtis
> Priority: Blocker
> Fix For: 2.1.1

> I have a simple example. A customer has a reference to an address and a
> (primary) contact (an extension of person). Find the customer, get the
> contact and evict it from L2. Now find the customer again using a new entity
> manager. Begin a Tx and change the address of the contact and then call
> Customer.getPrimaryContact() (this is important) Rollback the Tx. Now find
> the customer again using another new EntityManager and call
> Customer.getPrimaryContact().getAddress(). The address associated with the
> contact is Null and not the original address as expected. The same scenario
> works fine under OpenJPA 1.2.2.
> The reason this is a big problem for us is we use L2 caching in our
> application and the application is clustered. The same problem occurs if
> different nodes in the cluster operate on the same objects. In a cluster
> "evict" is not directly called, but the RemoteCommitProvider will evict the
> L2 and create the same problem.
> I have attached example code to reproduce the problem using a single JVM and
> calling Evict. I also have another example where you can deploy the code on
> two nodes in a cluster and see the problem occurs that way as well. Each
> example contains Unix shell scripts and Windows cmd files as well. Each are
> paired for JPA 1.0 and JPA 2.0. Again, the problem only occurs under JPA 2.0.
> This is a block for us. We cannot ship our product with this type of problem
> as it means objects and their graph can be corrupted.
