Hi @DamonFool ,

sorry I was on vacation and missed this PR.

in general it looks ok, but I can't help but wonder why have you replaced `-XX:MaxMetaspaceSize=8m` w/ `-XX:MetaspaceSize=10m -XX:MaxMetaspaceSize=20m`; won't removing `-Xmx` and adding `-XX:MaxRAMPercentage=25` be sufficient?

Thanks,
-- Igor
