Hi, Could I please get a review of this dead-code removal? During review of JDK-8244500 it was discovered that with the new cgroups implementation supporting v1 and v2 Metrics.getMemoryAndSwapLimit() will never return 0 when relevant cgroup files are missing. E.g. on a system where the kernel doesn't support swap limit capabilities. Therefore this code introduced with JDK-8236617 can no longer be reached and should get removed.
Bug: https://bugs.openjdk.java.net/browse/JDK-8247863 webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8247863/01/webrev/ Testing: Matthias tested this on the affected system and it did pass for him. Docker tests on cgroup v1 and cgroup v2. Thanks, Severin
