@iklam 
Thanks to review.
I updated the simulation

Simulation environment：
cgexec -g memory:foo java -XshowSettings:system -Xms60m -version （The successful running）
use -XX:+AlwaysPreTouch to simulate a long-running program
cgexec -g memory:foo java -XshowSettings:system -Xms60m -XX:+AlwaysPreTouch -version(killed by cgroup)
