Richard Hightower commented on CDI-14:

Peter et al, good points. So Instance is the way to do this, and if you expose and instance, you can use instance. Got it. 

Lincoln, We wrote a utility class as well and we use that a lot. I don't think we are normal users (in every sense of the word) :). 

I just think adding a couple of extra methods that hide the details of Instance is a good idea for an easier to use API.
I am guessing that not everyone wants to be an expert on CDI, but they may want to grab a bean.

I know I was quite surprised the amount of learning curve it took me to just look a bean up by name. I compare this to the Spring applicationContext, which does have these types of methods. I just think that BeanManager should have some easy to use facade methods to do common things.

There are a lot of people who don't care so much about instance and low level details of CDI. They just want a darn bean. :)
