Elasticsearch 7.5.1

while moving from ES7.2.0 to ES 7.5.1 have observed that the following JVM options thatwere present in ES 7.2 are not present in 7.5.

pre-touch memory pages used by the JVM during initialization

-XX:+AlwaysPreTouch

basic

explicitly set the stack size

-Xss1m

set to headless, just in case

-Djava.awt.headless=true

ensure UTF-8 encoding by default (e.g. filenames)

-Dfile.encoding=UTF-8

use our provided JNA always versus the system one

-Djna.nosys=true

turn off a JDK optimization that throws away stack traces for common

exceptions because stack traces are important for debugging

-XX:-OmitStackTraceInFastThrow

flags to configure Netty

-Dio.netty.noUnsafe=true
-Dio.netty.noKeySetOptimization=true
-Dio.netty.recycler.maxCapacityPerThread=0

log4j 2

-Dlog4j.shutdownHookEnabled=false
-Dlog4j2.disable.jmx=true

WIll the options still be respected if they were to be added to the jvm options file??
