I didn't quite understand the problem but you can cast a unique_ptr to shared_ptr (example).

@kelaicai Please open an issue here.

If you want to use the validator in different threads, just do so. When validating a JSON-document the validator-instance and the json-instance are considered const. Nothing is modified. So it is thread-safe.
