Copy Service does not works properly for Entities which extends Data Object and implements ExtensibleDataInterface

[swnsma]

Summary (*)

There is no way to use Extension Attributes in Copy Service if you are using entity class which extends DataObject

Examples (*)

magento2/lib/internal/Magento/Framework/Model/AbstractModel.php

Line 18 in 1e58f70

abstract class AbstractModel extends \Magento\Framework\DataObject

1. Create Extension Attribute for Quote Address.
2. Create Extension Attribute for Order.
3. Try to copy Extension Attribute from Quote Address to Order Extension Attribute with \Magento\Framework\DataObject\Copy.

Detected in magento/inventory#2309

Proposed solution

Change fallback from:

Array -> DataObject -> ExtensibleDataInterface -> AbstractSimpleObject
to
Array -> ExtensibleDataInterface -> DataObject -> AbstractSimpleObject
