From the document that I have followed, I understood that every element in EMF model to extend CDOObject. Is this mandatory to extend CDOObject? If yes, then I have an EMF model which is actually developed from other team and don't have permission to extend model class CDOObject. Is there any alternative solution in such case?? otherwise I would request them to update this changes particularly for me.
I have tried to save model elements without extending them to CDOObject, I have been getting Stackoverflow error. I want to be sure this is because of the code modification is required.

No, it's not strictly required. CDO also supports normally generated models (so called "legacy models").

Of course, it's better to regenerate the models particularly for CDO (so called "native models"). Only then you have the
scalability benefits and can scale your model instances to arbitrary sizes. Legacy models don't support lazy loading and
automatic unloading.

Maybe I can comment on the error if you show the stack trace...
