JVM does not detect that it runs in container and does not use container resource quotas

[MichaelNesterenko]

For some reason jvm does not detect container context and uses host resource quotas

Test command:

docker run -m 128m --rm --entrypoint sh adoptopenjdk/openjdk11-openj9:alpine -c "java -Xdump:java:events=vmstart -XX:MinRAMPercentage=20 -XX:MaxRAMPercentage=30 -XX:+UseContainerSupport -version && cat /java*"

Excerpt from the output:

1CICONTINFO    Running in container : FALSE

Full log output:
jvm-log.txt

@pshipton, looks like it, there is another host which uses cgroups v1 and jvm correctly sizes heap there.

Thanks. I'm going to close this as a dup then.
