Deadlock during serialization of entities [message #646152]

We are facing deadlocks during serialization of remote business method invocations on the server side.
Concurrent access on entities which are managed by a shared cache results in a deadlock during serialization of Vector as shown by the extract of a javacore at the bottom of this post.
The service is running on a WebSphere Application Server 6.1 incl. EJB 3.0 Feature pack. Version of EclipseLink is 2.1.1.

In the thread EclipseLink: Deadlock when returning Entities from a remote method call a similar problem is discussed and seems to be caused by the implementation of IndirectList.
In our environment neither on query nor on entity level read-only attribute is set but entities use lazy-loading relations of type java.util.List. Entities are read by a JPA EntitiyManager of a container managed service.

In the mentioned thread James (jsutherl) wrote:
Quote:
We should provide an option to use ArrayList in IndirectList instead of Vector...
Would this option be part of the related Bug 309822 - Deadlock when returning Entities from a remote method call and when would this option be available?

In the meantime we will replace List- by Set-based relations. Are other options available to avoid this kind of deadlock on JPA level?

Thanks,
Sven

I would recommend you vote for the bug and include you stack trace in the bug log.

You can set the collection class used for a mapping using a DescriptorCustomizer and mapping.useCollectionClass(ArrayList.class). Using a Set instead of List will also work.

You can change the global mapping default in ContainerPolicy.setDefaultContainerClass(ArrayList.class).

If you are using LAZY, IndirectList will still be used, which still uses Vector interally, so you could still have issues.

Do you mean IndirectList is still used for LAZY relations even if they are declared as Set?

No, IndirectList is only used for List.

IndirectSet is used for Set, which uses HashSet, so will not have the synchronization issue that Vector has.
