from Pact https://docs.pact.io/implementation_guides/jvm/matching
The following method is used to determine if two bodies match:
- If both the actual body and expected body are empty, the bodies match.
- If the actual body is non-empty, and the expected body empty, the bodies match.
- If the actual body is empty, and the expected body non-empty, the bodies don’t match.
- Otherwise do a comparison on the contents of the bodies.
