> In case of intensive usage there is an memory and CPU overhead in
> org.apache.aries.blueprint.proxy.Collaborator which can be easy eliminated:
> 1) Stack has a thread safety overhead, it can be replaced by ArrayDeque, the
> stack is used in a single thread
> 2) In case of there are no interceptors - it make sense to not allocate each
> time a Stack object. The reference can be set to null or a static immutable
> empty stack value.
