This can be reproduced on a linux based system using systemd as follows:

$ systemd-run --user --scope -p MemoryMax=512M ./build/linux-x86_64-server-fastdebug/images/test/hotspot/gtest/server/gtestLauncher -jdk ./build/linux-x86_64-server-fastdebug/images/jdk --gtest_filter=CollectorPolicy.young_scaled_initial_ergo_vm

We have devices with as little as 256M memory, which run JTreg (using a huge swap space).
