  8253714: [cgroups v2] Soft memory limit incorrectly using memory.high
  
  The early implementation of cgroups v2 support was done with
  crun 0.8 and it contained a bug which set memory.high over
  memory.low when --memory-reservation was being used as a CLI
  option.
  
  This bug has been fixed in later crun versions, starting with
  crun 0.11. Use memory.low in OpenJDK as well.
