providerStates missing from consumer contract in version 4.6.15

[markozz]

When I have a test with:

    @Pact(provider = "UserService", consumer = "UserConsumer")
    V4Pact getAllUsers(PactBuilder builder) {
        return builder
                .given("Users exist")
                .usingLegacyDsl()
                .uponReceiving("A request to get all users")
                .path("/api/users")
                .method("GET")
                .willRespondWith()
                .status(200)
                .headers(Map.of("Content-Type", "application/json"))
                .body("{\"2fd273a1-58f2-4409-a578-2bcadd8ab613\":{\"id\":\"2fd273a1-58f2-4409-a578-2bcadd8ab613\",\"firstName\":\"John\",\"lastName\":\"Doe\",\"dateOfBirth\":\"01-01-1970\"}}")
                .toPact(V4Pact.class);
    }

Then:

Actual:
The contract does not include a provider state for the interation

Expected:
Interaction includes attribute providerstate with value "User exist"

Specifying as follows does include provider state:

@Pact(provider = "UserService", consumer = "UserConsumer")
    V4Pact getAllUsers(PactBuilder builder) {
        return builder
                .given("Users exist")
                .expectsToReceiveHttpInteraction("A request to get all users", httpBuilder -> {
                    return httpBuilder
                            .withRequest(requestBuilder -> requestBuilder
                                    .path("/api/users")
                                    .method("GET"))
                            .willRespondWith(responseBuilder -> responseBuilder
                                    .status(200)
                                    .body("{\"2fd273a1-58f2-4409-a578-2bcadd8ab613\":{\"id\":\"2fd273a1-58f2-4409-a578-2bcadd8ab613\",\"firstName\":\"John\",\"lastName\":\"Doe\",\"dateOfBirth\":\"01-01-1970\"}}")
                                    .header("Content-Type", "application/json")
                            )
                            .comment("This is also a comment");
                })
                .comment("This is also a comment")
                .toPact();
    }
