Question

我在春季的代码是：

group = SysUtil.isLinux()?new EpollEventLoopGroup():new NioEventLoopGroup();

和代码块在这里，线程无法继续，我使用jstack，线程始终在这里，但是线程状态是可运行的：

"init_context_comm_t0" #14 daemon prio=5 os_prio=0 tid=0x00007f5fdc889800 nid=0x27 in Object.wait() [0x00007f5fd7ffc000]

复制步骤在spring初始化代码中，调用此代码：

group = SysUtil.isLinux()?new EpollEventLoopGroup():new NioEventLoopGroup();

网络版本

4.0.36.Final

JVM版本（例如java -version）

openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-8u141-b15-1~deb9u1-b15)
OpenJDK 64-Bit Server VM (build 25.141-b15, mixed mode)

操作系统版本（例如uname -a）

Linux debian 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) x86_64 GNU/Linux

提示：我在docker中运行此代码

这可能是一个错误...请在具有完整复制者的netty问题跟踪器中打开一个问题，以便我们看看。另外，您可能要升级netty版本，以排除尚未修复的版本。

Netty NetworkInterface.getNetworkInterfaces（）已阻止
