无名用户运行Arthas无法搜索到Java应用

[CeerDecy]

• [x] 我已经在 issues 里搜索，没有重复的issue。

环境信息

• arthas-boot version: 4.0.4
• java版本: java-1.8.0-openjdk-1.8.0.372.b07-1.el7_9.x86_64
• linux内核: 5.10.134-16.1.al8.x86_64
• Kubernetes版本：v1.30.1

重现问题的步骤

1. 以用户ID为1001，GroupID为1001，启动了一个java程序的容器，这个镜像里没有创建过ID为1001的用户

    securityContext:
      runAsGroup: 1001
      runAsUser: 1001

2. 执行arthas无法找到我运行中的java程序，但查看ps -ef确实是在运行中的

但如果这个用户创建过则可以正常执行（这个用户没有root权限）：

期望的结果

我希望在 Kubernetes Pod 中设置用户 ID 为 1001 时，能够正常使用 Arthas，尽管容器镜像中并没有为用户 ID 1001 创建相应的用户

实际运行的结果

实际运行结果，最好有详细的日志，异常栈。尽量贴文本。

Can not find java process. Try to run `jps` command lists the instrumented Java HotSpot VMs on the target system.

The error message suggests that the system cannot find a running Java process when you try to attach a monitoring tool, debugger, or profiler Possible Causes and Solutions:

1. Java Process is Not Running ✅ Solution: Run the command: jps -l If no Java process appears, start your Java application first.
2. jps Command Not Found ✅ Solution: Check if Java is installed and properly set up. Run: java -version If Java is not installed, install it.
3. JAVA_HOME is Not Set Correctly ✅ Solution: Set JAVA_HOME and update the system path. For Linux/macOS: export JAVA_HOME=/path/to/java export PATH=$JAVA_HOME/bin:$PATH
4. Java is Running as a Different User ✅ Solution: If running Java as a different user (e.g., root), try: sudo jps or switch to the Java process owner
5. JDK is Not Installed (Only JRE is Installed) ✅ Solution: jps comes with the JDK, not the JRE. If you only have JRE installed, install the JDK. Check JDK installation: which jps
6. jps is Blocked by Security Policies ✅ Solution: Try running: jps -v If permission issues exist, try executing with admin/root privileges. Final Check After applying the solutions, run jps
