OK. Thanks for the grammatical correction. Here is the revised webrev.01:

throw new UnsupportedOperationException(nodeType
+ "is not designed for extensibility by application.");
Missing a space after the node type. Also, to match the docs in JDK-8158006 I recommend something more like:
"Applications should not extend the " + nodeType + " class directly"

Can you similarly fix the messages in CameraHelper and LightBaseHelper to match? They are grammatically incorrect.

After the encapsulation work is done, if an application extends Node, Shape, or Shape3D directly, Node.getHelper will return null, which means that the caller of the NodeHelper with get an NPE. The task here will be to check for null in getHelper() itself and throw UnsupportedOperationError with a meaningful error message.
