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]
     ^            ^
