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

At the end of the day MDR still does reflection, see
org.jboss.metadata.plugins.loader.reflection.AnnotatedElementMetaDataLoader.
Performance wise it's even worse because it scans for methods / fields
and such to match a signature.
So what used to be fast with advisor.resolveAnnotation(method,
annotationType) is now horribly slow, because of MDR. Which is a bummer,
because almost every interceptor we've got does something like that.
