BUG: semicolon is not handled correctly in headers by au.com.dius.pact.consumer - junit5 version:4.6.3

[vasile21]

Hi I am migrating to latest pact-consumer library:

<dependency>
   <groupId>au.com.dius.pact.consumer</groupId>
   <artifactId>junit5</artifactId>
   <version>4.6.3</version>
</dependency>

My PactDsl creation looks like:

return pactDslWithProvider
        .given("myProviderState")
        .uponReceiving("interactionDescription")
        .path("/path/resource/blabla")
        .method("POST")
        .headers(setRequestHeaders())
        .body("{\"anyField\":\"anyResource\"}")
        .willRespondWith()
        .status(400)
        .headers(setResponseHeaders())
        .body(matcherRules(getResponseBody()))
        .toPact();

private Map<String, String> setResponseHeaders(){
Map<String, String> headers  = new HashMap<>();
    headers.put(
        "strict-transport-security, "max-age=3600; includeSubDomains; reload");
    headers.put("Content-Security-Policy", "default-src: 'none'; frame-ancestors 'none'; base-uri 'self'");
//other headers...
}

In the older version of pact headers that contained semicolon were handled correctly in pact file:

 "response": {
        "status": 400,
        "headers": {
          "Content-Security-Policy": "default-src: 'none'; frame-ancestors 'none'; base-uri 'self'",
          "strict-transport-security": "max-age=3600; includeSubDomains; reload",
        },
        "body": {
         //....

Pact file after the upgrade contains invalid values for headers as can be seen below:

 "response": {
        "status": 400,
        "headers": {
          "Content-Security-Policy": "default-src: 'none'; frame-ancestors 'none'=\"\"; base-uri 'self'=\"\"",
          "strict-transport-security":  "max-age=3600; includeSubDomains=\"\"; reload=\"\"",
        },
        "body": {
         //....

Could you let me know if this will be fixed or if there is any workaround for this issue?
