No, it is just confusing.
Note the CD-based annotation @RequestScoped. CDI is enabled and that
annotation informs the runtime an instance of the class ActorResource
will be instantiated and managed by CDI in the scope of the HTTP
request.
The use of @ManagedBean is slightly different and will work in CDI and
non-CDI enabled environments. An annotated class with @ManagedBean
means that Jersey will defer to the container to instantiate the class
but Jersey will manage the bean. It is basically a way of getting EE-
realted stuff injected.
The "managed bean" term is defined to unify the many forms of managed
bean that are available in EE.
