> JVM will never have PID 1
JVM can certainly be PID 1 inside a container. Example:
```
$ cat App.java
public class App {
public static void main(String... args) {
var mxBean =
java.lang.management.ManagementFactory.getRuntimeMXBean();
System.out.println(mxBean.getName());
}
}
$ docker run -it --entrypoint java -v `pwd`:/tmp/ openjdk:21 /tmp/App.java

```
> checking `/proc/1/environ` and the environment of the JVM is equivalent.
Yes, equivalent but perhaps reading from `System.getenv()` is a slight
improvement by avoiding file i/o on procfs
