Internal server error and failure to connect

[jwi...@lifelink.com]

I'm trying to run WireMock 2.1.12 in a Grails project.

The code I'm testing:

    rest.post('http://127.0.0.1/8090/rest/orders/v1/submission'){
      auth getEnv('questUsername'), getEnv('questPassword')
      contentType "application/json"
      json {
        documentTypes = "REQ"
        orderHl7 = this.toHl7Base64()
      }
    }

The WireMockServer test in spock, I've configured it to respond on port 8090:

    WireMockServer wireMockServer = new WireMockServer(
            options().port(8090)


    wireMockServer.start()


    stubFor(post(urlMatching(/rest\/orders\/v1\/submission/))
            .willReturn(aResponse()
            .withStatus(200)
            .withHeader("Content-Type", "application/json")
            .withBody('whee!')
            ))

When I execute the spock test, I get:

    com.github.tomakehurst.wiremock.client.VerificationException: Expected status 201 for http://localhost:8080/__admin/mappings/new but was 500

      at com.github.tomakehurst.wiremock.client.WireMock.stubFor(WireMock.java:84)

I created a file in: src/test/resources/mappings/new with some mapping data per the docs.  Same error.

When I hit http://localhost:8080/__admin, I get json indicating

 {"message":"Internal server error","error":500}

I found 2 java processes on 8080 and kill them both:

java    13705  440u  IPv6 0xa3f8c124b8967d3f      0t0  TCP localhost:59886->localhost:http-alt (CLOSE_WAIT)
java    13749  154u  IPv6 0xa3f8c124b896c31f      0t0  TCP *:http-alt (LISTEN)

When I re-run the test I get:

org.apache.http.conn.HttpHostConnectException: Connect to localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused

The java processes are no longer running.

Any idea whats going on?
