Here, the DefaultBuildContext (and its contract interface BuildContext) got erroneously loaded from the core realm instead of the plugin realm.
The error is due to bad management of the container's lookup realm and only manifests itself for the first mojo execution of a build.
Other potentially affected plugins are those using plexus-sec-dispatcher, plexus-cipher or any other components that aren't filtered out of the plugin realm and where the component is looked up via PlexusContainer.lookup(String), i.e. without actual type as role.
