That is an old snapshot of aop-mc-int. You should use the one here instead:
Anything that is a snapshot version should be in the snapshots repository, and not in the regular repo. I'll remove that version from repository.jboss.org, since it shouldn't be in there.
There are some other 2.0.0-SNAPSHOT versions of microcontainer components in the releases repository (container, kernel, dependency, etc). I'm going to remove those also as long as no one has any objections.
