> 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.
