      Description

      Right now, users have to add their jars to the NM classpath directly, thus put them on the system classloader. But if multiple versions of the plugin are present on the classpath, there is no control over which version actually gets loaded. Or if there are any conflicts between the dependencies introduced by the auxiliary service and the NM itself, they can break the NM, the auxiliary service, or both.

      The solution could be: to instantiate aux services using a classloader that is different from the system classloader.
