	// We never want to serialize the top-level value "null," since it's not a
	// valid JOSE message. But if a caller passes in a nil pointer to this method,
	// MarshalJSON will happily serialize it as the top-level value "null". If
	// that value is then embedded in another operation, for instance by being
	// base64-encoded and fed as input to a signing algorithm
	// (https://github.com/square/go-jose/issues/22), the result will be
	// incorrect. Because this method is intended for known-good objects, and a nil
	// pointer is not a known-good object, we are free to panic in this case.
	// Note: It's not possible to directly check whether the data pointed at by an
	// interface is a nil pointer, so we do this hacky workaround.
