Maven plugin execution isolation

 Maven2 takes advantage of Plexus' ability to execute a component using a
 ClassWorlds ClassRealm that is populated with the JAR containing the
 component in question and all of its dependencies. Using ClassWorlds
 notation for realms we have the following:

+-----+
      [plexus.core]
            ^
            |
   [plexus.core.maven]
     ^            ^

    precisely control parts of the extension and dependencies to expose in the API class loader.
    Maven uses Plexus Classworlds to build the class loader hierarchy, therefore some concepts used in this extensions
    stem from Plexus Classworlds originally.
