java.io.IOException：无法在Play Framework中的通道java.nio.channels.SocketChannel上编写

Question

我正在尝试使用multipart / form-data将字节数组上传到远程WS！使用Scala的框架。我的代码是：

    //create byte array from file
    val myFile = new File(pathName)
    val in = new FileInputStream(myFile)
    val myByteArray = new Array[Byte](audioFile.length.toInt)
    in.read(audioByteArray)
    in.close()    

    // create parts 
    val langPart = new StringPart("lang", "pt")
    val taskPart = new StringPart("task","echo")
    val audioPart = new ByteArrayPart("sbytes", "myFilename", myByteArray, "default/binary", "UTF-8")

    val client: AsyncHttpClient = WS.client
    val request = client.preparePost(RemoteWS)
                        .addHeader("Content-Type", "multipart/form-data")
                        .addBodyPart(audioPart)
                        .addBodyPart(taskPart)
                        .addBodyPart(langPart).build()
    val result = Promise[Response]()

    // execute request 
    client.executeRequest(request, new AsyncCompletionHandler[AHCResponse]{
      override def onCompleted(response: AHCResponse): AHCResponse = {
        result.success(Response(response))
        response
      }
      override def onThrowable(t: Throwable) {
        result.failure(t)
      }
    })

    // handle async response
    result.future.map(result =>{
      Logger.debug("response: " + result.getAHCResponse.getResponseBody("UTF-8"))
    })

每次执行此请求时，都会抛出此异常：

java.io.IOException：无法在通道上编写java.nio.channels.SocketChannel

远程服务器没问题，我可以使用例如Postman来发出成功的请求。

我正在使用Play Framework：

播放使用Scala 2.10.3构建的2.2.3（运行Java 1.8.0_05）

AsyncHttpClient的版本：

com.ning：异步-HTTP客户端：1.7.18

欢迎任何帮助！
