Stuart Douglas moved SOLDER-106 to SEAMPERSIST-50:
--------------------------------------------------
Project: Seam Persistence (was: Seam Solder)
Key: SEAMPERSIST-50 (was: SOLDER-106)
Affects Version/s: 3.0.0.Final
(was: 3.0.0.Final)
> Seam transaction potential memory leaks if there is nested
> @TransactionAttritue

> Key: SEAMPERSIST-50
> URL: https://issues.jboss.org/browse/SEAMPERSIST-50
> Project: Seam Persistence
> Issue Type: Bug
> Affects Versions: 3.0.0.Final
> Environment: Windows, Eclipse, jboss AS 6 Final
> Reporter: yangju
>
> I have been doing some performance testing on cdi beans with
> @TransactionAttribute in jboss AS 6 final. After my application runs non-stop
> for a while (I have created 10 threads constantly invoking the
> ApplicaitonScoped bean to get data from database and then update those data),
> I got got exception:: java.lang.OutOfMemoryError: GC overhead limit exceeded.
> This happened when I have Bean A injects Bean B and both A and B are
> annotated with @TransactionAttribute.
> These two beans looks up (instead of injecting) entity manager from an entity
> manager factory (jndi lookup emf first, then emf.createEntityManager()).
> These beans are not declared as session bean and no SMPC is used. I thought
> transaction will be propagated from one bean to another, or it only does that
> for stateful session beans or SMPC? If I remove one of the
> TransactionAttribute annotation from B then the OOM problem does not occur.
> This OOM problem also occurs after my application runs for a while in this
> scenario:
> Bean A injects Bean B and Bean C; Bean C injects Bean B.
> I analyzed the heap dump with eclipse memory analyzer and it suspects that
> the seam 3 transaction interceptor might have memory leaks.
> I used Eclipse Memory Analyzer to analyze the heap dump when OOM occurred. It
> says:
> One instance of "org.jboss.weld.context.CreationalContextImpl" loaded by
> "org.jboss.classloader.spi.base.BaseClassLoader @ 0xd2b85a08" occupies
> 387,677,848 (40.99%) bytes. The memory is accumulated in one instance of
> "java.lang.Object[]" loaded by "<system class loader>".
