Why not T Component.getInstance(Class<T> clazz) ?

[atzbert]

This is no real issue it's just for my interest, I strongly believe there must be a reason for this. It's just that I don't get it :). Maybe someone can help me out here:
I catch myself quite often overriding methods which are offered by Seam and look like

Object Component.getInstance(Class clazz)

with the corresponding generalized implementation

<T> T Component.getInstance(Class<T> clazz)

Why is it not implemented like that per default?, it would safe quite a few casts I guess...

Because for session bean components, the component class is the bean class, but the client view is the local interface.

I knew there was a reason...and it even makes sense. Thanks for the explanation. Guess I have successfully shown off my lacking experience with enterprise beans :)
