[jdk11u-dev] RFR: 8265836: OperatingSystemImpl.getCpuLoad() returns incorrect CPU load inside a container

Tue Jun 8 10:08:21 UTC 2021

JDK-8265836 applies to OpenJDK 11u as well. Patch applies clean. The only difference is in context. JDK head changed method `getCpuLoad()` while the JDK 11u backport changes `getSystemCpuLoad()` as that name hasn't been changed when the OperatingSystemMXBean has been made container aware in 11u.

Testing: Manual using the reproducer of the bug. See the backport bug for details.
