Romain, that's not true. Tomcat by default ALWAYS serializes the session at shutdown!
Even if you don't have a cluster set up. This is also required by the Servlets
spec...

Typically the case I care here is default tomcat one (+ embedded
tomcat* ones) where session is never serialized so this constraint is
not needed at all. That said having a SPI to add a serializer by bean
(or default one) to avoid this constraint is awesome as well.
