This should be served by MDR (metadata repository) subproject of MC:

http://anonsvn.jboss.org/repos/jbossas/projects/jboss-mdr/trunk/

...which as I understand is able to collect type information without the 
need for classloading (via Javassist).

Something I'd discussed a bit with Ales awhile back is refactoring 
jboss-metadata to instead of using reflection a la:

http://anonsvn.jboss.org/repos/jbossas/projects/metadata/trunk/src/main/java/org/jboss/metadata/annotation/creator/AbstractProcessor.java

...to instead read from MDR.  I admittedly haven't yet digged too much 
here, but since you ask the question... ;)
