As it was mentioned in comments on JBPAPP6-1450 I'm creating upstream jira for this feature.
It would be fine to have possibility to control settings of cache for stateful beans in EJB3 susbsystem.
Currently there is possible to set up pool for stateless beans but there are no settings possibilities for SFSB.
What I'm missing is the possibility how to define default cache for the stateful beans and how to create and manage things which cover tag <caches> from ejb3 subsystem.
I mean that you can define cache-ref for SFSB and you can set up cache properties in EJB subsystem (eg. <cache name="passivating" passivation-store-ref="file" aliases="SimpleStatefulCache"/>) in standalone.xml or via cli (jboss-cli.sh) but this possibility is not accessible in web admin console.
