title: okhttp3.OkHttpClient - A connection to any_host was leaked.Did you forget to close a response body?
body: <p>In my Kotlin's project I use <code>okhttp3</code></p>
  
  <p>Here example to connect to remote host:</p>
  
  <pre><code>    import okhttp3.*
      import okhttp3.logging.HttpLoggingInterceptor
  
  var оkHttpClient = OkHttpClient()        оkHttpClient.newCall(requestNegotiate).enqueue(object : Callback {
               override fun onResponse(call: Call, response: Response) {
                    ...
               }}
  </code></pre>
  
  <p>and is's work fine.</p>
  
  <p>But after few minutes I get many times the next message:</p>
  
  <pre><code>  2019-02-13 18:39:39,197 675399 [OkHttp ConnectionPool] WARN  okhttp3.OkHttpClient - A connection to any_host_com was leaked. Did you forget to close a response body? To see where this was allocated, set the OkHttpClient logger level to FINE: Logger.getLogger(OkHttpClient.class.getName()).setLevel(Level.FINE);
  </code></pre>
