[totemofwolf]

• [x] 我已经在 issues 里搜索，没有重复的issue。

环境信息

• pod/docker 里的 arthas 安装办法：

dpkg -i arthas-3.3.2.deb
apt --fix-broken install
dpkg -i arthas-3.3.2.deb

• arthas-boot.jar 或者 as.sh 的版本： 3.3.2
• Arthas 版本: 3.3.2

• 操作系统版本: $ cat /etc/os-release
  PRETTY_NAME="Debian GNU/Linux 10 (buster)"
  NAME="Debian GNU/Linux"
  VERSION_ID="10"
  VERSION="10 (buster)"
  VERSION_CODENAME=buster
  ID=debian
  HOME_URL="https://www.debian.org/"
  SUPPORT_URL="https://www.debian.org/support"
  BUG_REPORT_URL="https://bugs.debian.org/"

• 目标进程的JVM版本: $ java -version

• 执行arthas-boot的版本: xxx

重现问题的步骤

1. 切换到 deploy 用户 # su - deploy

$ export JAVA_HOME=/usr/local/openjdk-8
$ export JRE_HOME=/usr/local/openjdk-8
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_HOME/lib:/app/yyyy/lib
$ export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
$ export PATH=$PATH:$JAVA_HOME/bin

OK，看到了钉钉中的回复：提到这个 issue:
设置环境变量_JAVA_OPTIONS 导致启动失败

问题原因明白了：因为我们的 pod 启动时插入了 JVM 环境变量 JAVA_TOOL_OPTIONS 导致 as.sh 脚本执行到 java -version 时候卡住：

# jps
Picked up JAVA_TOOL_OPTIONS: -javaagent:/rasp/rasp.jar -javaagent:/skywalking/agent/skywalking-agent.jar

说一下我的解决办法：

0、安装 arthas-3.3.2.deb
1、从 基础镜像 openjdk:8-jdk-slim 拷贝 /usr/local/openjdk-8 放入线上的 容器（基于openjdk:8-jre-slim） 的 /tmp/ （比如使用 lrzsz 工具）
2、修改 as.sh 脚本添加：
export JAVA_HOME=/tmp/openjdk-8
export PATH=/tmp/openjdk-8/bin:$PATH
unset JAVA_TOOL_OPTIONS

3、切换到 APP 运行时用户：su - deploy ，然后重新执行 as.sh
