Java WireMock定义存根在Cucumber并行执行的多线程测试中失败

我有Spring—Boot应用程序和集成测试，使用Cucumber和WireMock. 在常规的非并行执行模式下执行测试工作正常，没有任何问题，但是当切换到并行执行模式时，测试开始失败.例外情况:

com.github.tomakehurst.wiremock.common.JsonException: 
{
  "errors" : [ {
    "code" : 10,
    "source" : {
      "pointer" : "/code"
    },
    "title" : "Error parsing JSON",
    "detail" : "Unrecognized field \"code\" (class com.github.tomakehurst.wiremock.common.Errors), not marked as ignorable"
  } ]
}

    at com.github.tomakehurst.wiremock.client.WireMock.stubFor(WireMock.java:119)

WireMock.stubFor应该是线程安全操作吗？基于例外，看起来没有.如果不是线程安全的，有哪些解决办法(同步/锁定stubFor的所有执行)？

stub初始化示例:

WireMock.stubFor(post(urlPathMatching("/test"))
    .withRequestBody(equalToJson(..))
    .willReturn(aResponse()
        .withStatus(200)
        .withHeader("Content-Type", "application/json")
        .withBody(..)));

WireMock的创建方式如下:

WireMockServer wireMock = new WireMockServer(options()
    .port(8000)
    .extensions(new ResponseTemplateTransformer(true))
    .notifier(new ConsoleNotifier(true)));
wireMock.start();
configureFor(8000);
