Description

I got -1.0 from both CpuLoad and SystemCpuLoad in OperatingSystem MXBean when I run the application on Fedora 33 x64 which is installed cgroups V2. Please see the attached image which I captured JConsole.

I do not run the application in the container, nor do not run with resource limitation on cgroups, so JMX should report CPU load on host value in this case.
