> The lock counting in org.jboss.ejb.EnterpriseContext is not synchronized.
> The lock ivar is not even volatile.
> This variable needs replacing with synchronized method blocks or an oswego concurrent SynchronizedInt.
> This bug could either cause passivation to be invoked when it shouldn't or vice versa.
> Additionally, even with this fix, the usage in StatefulSessionInstanceInterceptor needs replacing with something more atomic!
>             if (!ctx.isLocked())
>             {
>                
>                //take it!
>                ctx.lock();
>             }
