 In some clear cases it's not supported and this has not changed in CDI
1.1. However it's never been a limiting factor for me at least since i
normally don't really use dependent beans or any other non normalscoped.
>From the CDI 1.1 spec:

the container is required to support circularities in the bean dependency
graph where at least one bean participating in every circular chain of
dependencies has a normal scope, as defined in [normal_scope]. The
container is not required to support circular chains of dependencies where
every bean participating in the chain has a pseudo-scope.
