JVM minArrayLike matching rules

I'm just getting started with pact and am running into issues with array matchers.

I have the following pact fragment, and it generates

@Pact(consumer = "idm-client")
public PactFragment getUsersFragment(PactDslWithProvider builder) {
    return builder
            .given("a user with an id named 'user' exists")
            .uponReceiving("get all users")
            .path("idm/user")
            .method("GET")
            .willRespondWith()
            .status(200)
            .body(new PactDslJsonArray()
                    .minArrayLike(1)
                    .uuid("id")
                    .stringType("username")
                    .stringType("email")
                    .closeObject())
            .toFragment();
}

and it generates a pact file like this

    "interactions": [
        {
            "providerState": "a user with an id named 'user' exists",
            "description": "get all users",
            "request": {
                "method": "GET",
                "path": "idm/user",
                "body": null
            },
            "response": {
                "status": 200,
                "headers": {
                    "Content-Type": "application/json; charset=UTF-8"
                },
                "body": [
                    {
                        "email": "dnpVDMuTXwIduMLiOTKg",
                        "id": "946e570b-386d-4a22-b5cc-a0b429f063aa",
                        "username": "vhICeWvqPNYeZErsIWkZ"
                    }
                ],
                "matchingRules": {
                    "$.body[*].username": {
                        "match": "type"
                    },
                    "$.body[*].email": {
                        "match": "type"
                    },
                    "$.body[*].id": {
                        "regex": "[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"
                    }
                }
            }
        }
    ],Enter code here...

I would expect something in the matching rules to specify the minimum array size, but that doesn't seem to be the case.

Changing it to minArrayLike(5) doesn't change the pact file, nor does changing it to maxArrayLike(1) or maxArrayLike(5).

This is causing my provider tests to fail in an unexpected manner.

The provider is currently returning 2 users, and the test fails because it only expects 1. (using pact-jvm-provider-spring-mvc).

java.lang.AssertionError: []: Expected 1 values but got 2

The error message isn't very useful on it's own, but I was able to verify by debugging that it failed because the provider had 2 items in the response, but the expected payload only had 1.

What exactly are minArrayLike and maxArrayLike supposed to do?
