Description

I'm working on a kodo plugin in the codehaus mojo sandbox. Using 2.0, it works fine. In 2.1, it can't find xercesImpl, which is a transitive dependency of the plugin. Did something change to cause new behavior (aka a bug) related to this? Just eyeballing the info below, in 2.0, the instance of classloader was org.codehaus.classworlds.RealmClassLoader but in 2.0.1 it is org.codehaus.plexus.util.RealmDelegatingClassLoader

I tried specifying xercesImpl as a direct dependency and that didn't work either so I'm not sure it's related to the transitivity.

Output from 2.0.1: (2.0 follows further below)
