docs: Will pick the best instantiator for the provided class. If you need to create a lot of
  instances from the same class, it is way more efficient to create them from the same
  ObjectInstantiator than calling {@link #newInstance(Class)}.
  
  @param <T> Type to instantiate
  @param clazz Class to instantiate
