Okay, I am fine with this.

> It's already there? This has been added with https://bugs.openjdk.org/browse/JDK-8227006 and https://bugs.openjdk.org/browse/JDK-8232207. The current code doing it for CPU is [here](https://github.com/openjdk/jdk/blob/96a0502d624e3eff1b00a7c63e8b3a27870b475e/src/hotspot/os/linux/cgroupSubsystem_linux.cpp#L562-L584) and for memory it's [here](https://github.com/openjdk/jdk/blob/master/src/hotspot/os/linux/cgroupSubsystem_linux.cpp#L595-L607). It's only been done for the core metrics, though.

Thanks for pointing it out. Somehow I missed it.

And thanks for running through the scenario.
