I think you misunderstood me, I asked Mark (or anyone) to file an issue so that we can specify this ;-) I'm not doing it right now as I'm in the middle of refactor of Infinispan ;-)

From a user perspective it would be convenient to be able to do a beanManager.getBeans(Instance.class). That is the only way currently to list all available Beans, which is needed from time to time. Since I am always a fan of seeing things from the users perspective, so why not specifying this?
