[jboss-dev] AS5 startup time

[Ales Justin]

It should get even better. :-)
I'm pushing for MetaData Creators additional information:
  - http://www.jboss.com/index.html?module=bb&op=viewtopic&t=138689

I re-factored my annotation scanning to be completely lazy (it was 
already pretty much lazy :-), exposing the minimal info possible, until 
you actually require the full package.

I'll try providing already acquired annotation value/information - 
making it optional, since you can always retain it from owner and signature.

But yeah, no performance surprise there if the app involved doesn't have 
a lot of JEE stuff in it - AltAnnMDD picks up a lot less classes for 
Creators to scan.
