Carlo de Wolf commented on EJB_SPEC-56:
---------------------------------------
http://docs.oracle.com/javaee/6/api/javax/ejb/StatefulTimeout.html#value%28%29
A value of -1 means the bean will never be passivated due to timeout.

> 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.

> @Target({ElementType.METHOD, ElementType.TYPE})

> public @interface NotPassivable {
