(已解决！通过伪造系统随机生成器，详见下文)
我正在为我的开发/构建团队设置一个虚拟机镜像。在该虚拟机中应该运行一个Weblogic域。我使用的是Ubuntu服务器发行版，WLS 9.2MP3 + ALSB。
一切都正常工作，速度相当快，但是在启动时，WLS会停止两次，每次停顿时间可测量，总共约有10分钟的延迟。对于需要服务器重启的部署任务来说，这非常令人烦恼。:-(
睡眠时间不是恒定的，有时服务器启动得非常快，有时一般，有时10分钟或更长时间。
有趣的是，如果我在查看停止的服务器时按Enter键，它会更快地唤醒，有时几秒钟后就能启动。当在VM中执行时，WLST（Weblogic Jython shell）也会挂起相当长的时间。虽然它不会响应Enter键。
这里一定有一些开发人员使用VM运行WLS。我想知道其他人是否有同样的问题？有人能够解决吗？
以下是服务器输出（只供参考）：

我认为我找到了问题所在：可能是随机种子的初始化。这可能解释了为什么生成键盘事件会释放服务器。我已经进行了线程转储，一个线程处于可运行状态，但正在等待：
