    Calling SFSB in no transaction is locked after few attempts

    Albert Dabrowski Newbie

      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?
