Description: This change adds a defensive safeguard to the deserialization logic in Utilities.cloneObject(). Previously, the custom ObjectInputStream.resolveClass() method loaded classes using Class.forName() without validating that the resolved class matched the expected object type. If untrusted or malformed serialized data were ever passed to this code path, this could allow unexpected classes to be resolved during deserialization. The updated implementation verifies that the resolved class is compatible with the original object’s class and rejects incompatible classes early. This keeps the existing behavior for valid use cases while adding an extra layer of safety.
