Dear JVM experts, Regarding to https://gist.github.com/erikdw/e730a1249887bb4462f226658351cfa4, we can set -XX:MinMetaspaceFreeRatio=0 & -XX:MaxMetaspaceFreeRatio=100 to disable dynamic resize metaSpace (changing high-water mark) which could trigger full gc. But when i set the following metaspace related java opts(MetaspaceSize and MaxMetaspacesize is 2g), reserved MetaspaceSize is still 1G which is same as the default behavior(didn't set any metaSpace related java opts, MetaspaceSize is ~20M). Could u please kindly provide help? Thx in advance!
