The method DefaultClassFactory.newInstance(Class<T>, Object...) calls ConstructorUtils.invokeConstructor(Class, Object[]) while this is not the case for DefaultClassFactory.newInstance(Class<T>, Class<?>[], Object...).

This is especially a problem if you have more precise constructors in subclasses (especially if you use generics).

Example: after introducing generics for models (MAGNOLIA-3081) the method AbstractRenderable.newModel(...) fails to find the correct constructor.
