Anyone have issues with Ktor's 1.0.0-rc apache client? I have a client defined as follows:

private val client = HttpClient(Apache) {
    expectSuccess = false
    install(JsonFeature) {
      serializer = JacksonSerializer()
    }
  }

and during an upload using WriterContent as the body, ktor hangs, and the app suspension point never resumes, with the stack:

Same code defined with CIO.config { } instead of Apache works fine...
