[jdk8u-dev] RFR: 8287107: CgroupSubsystemFactory.setCgroupV2Path asserts with freezer controller

Tue Dec 20 18:09:34 UTC 2022

Not a clean backport due to changes in test - `Files.writeString(a, b)` => `Files.write(a, b.getBytes())` - and some copyright and `@bug` lines. Fixed manually.

Testing: Linux x86_64 fastdebug (reg-test fails prior and passes after product fix).
