I have checked in the change:
1. Use @Replicable annotation.
2. It applies to sub-class as well. If user doesn't want to apply it to sub-class, he can change in pojocache-aop.xml from:
<prepare expr="field(* $instanceof{@org.jboss.cache.pojo.annotation.Replicable}->*)" />
<prepare expr="field(* @org.jboss.cache.pojo.annotation.Replicable->*)" />
