First I compiled org.codehaus.plexus:plexus-container-default:jar:1.0-alpha-10
(I modified the pom, removing SNAPSHOT then isntalled it locally, to be sure that I was the only one with the latest version).
Second I forced maven-components/integration-tests/maven-core-it-plugin
to depend upon the alpha-10 version of the jar:

But when I,look at the plexus-container-default code. there are no lines that match the stacktrace.
E.g. ObjectWithFieldsConverter l 137 doesn't exist.
Where does this other version of the component come from and how to force it to alpha-10 ?
