Can someone direct me to a working example of how this gets used.
I am still unsure exactly how this works supposedly if the super class of a class was not stored in the ObjectOutputStream and upon readObject() execuiting  somehow this kicks in either within the class being deserialized and/or its super class?

An example would really make this a lot clearer. Does anyone have such a sample source code file?

hard to give an example. Its to handle deserializing an object where the a superclass has been added since it was serialized. By default it will initialize the fields to default values. readObjectNoData() provides a hook to override this behaviour
