@Stuart: api validating or enforcing classloader in mojo need workarounds since you will use javax.inject from maven and not from your mojo container/code (embedding an OSGi container can have this issue in some cases without much hack but most container using classloaders will hit it, I hit it at talend for component framework, some tomcat extensions as well etc...). Nothing theorical and even if it would be theorical, we have to respect out mojo design right? so we can't do that anyway until we assume to maintain it and not move to jakarta anytime soon without a classfiletransformer maintaining the mapping which is something which was requested to be avoided on maven 4 path IIRC.
