输入java -version 提示警告
OpenJDK 64-Bit Server VM warning: Deactivate UseIOPrioritySizePolicy due to failed to parse cpu stat
openjdk version "1.8.0_422"
OpenJDK Runtime Environment (Alibaba Dragonwell Extended Edition 8.20.21) (build 1.8.0_422-b01)
OpenJDK 64-Bit Server VM (Alibaba Dragonwell Extended Edition 8.20.21) (build 25.422-b01, mixed mode)

使用Alibaba_Dragonwell_Standard_8.20.21_x64_windows.zip，输入java -version 没有警告了，如果使用Alibaba_Dragonwell_Extended_8.20.21_x64_windows.zip，输入java -version 就有警告，如何消除警告？

@qingzhoufanyue 你好，不好意思这个日志给你带来困扰了

  1. 首先它只是一个日志的报错提醒，不影响功能的正常的使用的
  2. UseIOPrioritySizePolicy这个特性不支持windows，应当在windows平台自动关闭相关日志，但是我遗漏了这件事。我会在下一次发布时补上
