> > Stateful Session Beans can be passivated (and so often serialized) by the
> container to disk to save resources. This behavior can lead to problems with
> performance, scalability and even robustness of the application. A SFSB may
> contain non-serializable attributes which prevent a successful serialization and
> lead to runtime exceptions.
> > Proposal: introduction of @NotPassivable annotation (TODO: suggest better
> name) to prevent passivation of SFSB. SFSB denoted with this annotation should
> never be passivated and the methods ejbActivate and ejbPassivate never
> invoked. In an overload scenario the container is supposed to destroy the SFSB
> instances, instead of passivating them.
