@jerboaa Thanks a lot for the thorough investigation here!
I was also able to reproduce the failure locally on my Ubuntu 24.04 using
`podman` (that runs containers as a regular user):
sudo apt install podman
make test
TEST="jtreg:test/hotspot/jtreg/containers/docker/TestJcmdWithSideCar.java"
JTREG="JAVA_OPTIONS=-Djdk.test.container.command=podman"
...
STDERR:
java.lang.RuntimeException: ACCESS_TMP_VIA_PROC_ROOT: Could not find specified

Whereas with `docker` (that runs containers as `root` by default) the test
passes:
make test
TEST="jtreg:test/hotspot/jtreg/containers/docker/TestJcmdWithSideCar.java"
JTREG="JAVA_OPTIONS=-Djdk.test.container.command=docker"

With `podman` and the changes in this PR, the test works again.

Thanks for trying to improve this too, it was quite annoying to have to wait so
long for each test run.. đ
However, when I'm running the test with `docker` with the changes from this PR
(`make test
TEST="jtreg:test/hotspot/jtreg/containers/docker/TestJcmdWithSideCar.java"
JTREG="JAVA_OPTIONS=-Djdk.test.container.command=docker"`) I get a new failure:
[docker-failure.log](https://github.com/user-attachments/files/17227971/docker-failure.log).
If I revert the test runtime optimization (and keep the disabling part) the
test works with `docker` again.
