Hi,
I come accross a strange behaviour regarding SFSB on new AS7.1.1. After few calls on business method the consecutive call is locked and cannot acquire a lock thus it eventually exit on the timeout.
The key is that this SFSB is NOT in transaction which seems cauing a problem. I changed that bean to be in transaction and works ok. Anyway finally I need a solution with transaction attribute NotSupported.

Could anyone confirm if there is a problem so might be raised ot JIRA or have missed something?

Configuration:
AS 7.1.1 (anyway tested also on the latest 7.2.0 Alpha1 and had the same problem)

On Class:
@Stateful
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
@Cache("NoPassivationCache")
public class ....

After taking a thread dump it revelas the following below. Seems a problem in the StatefulSessionSynchronizationInterceptor?
