Windows-Server-2012
Jenkins Slave 在建構期間離線
在 Windows Server 2012 上安裝了 Jenkins 1.651 master 和 slave。slave 專用於執行 Selenium 測試，但大多數時候它會離線：

可能的解決方案
基於此 source，堆棧跟踪的一部分：
at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)並且在辦公室中遇到同樣的問題，將 jdk7 升級到最新的 oracle-jdk8 可以解決這個問題。
如果問題仍然存在：
- 請準確說明問題發生的時間，以便可以重現問題
- 請添加導致問題的建構的 Jenkins 建構日誌。也許有一個特定的任務由導致問題的作業執行。
- 建構作業時查看 windows 任務管理器
- 請添加成功建構之一的日誌和失敗建構之一的日誌
