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



explicitly set the stack size


set to headless, just in case


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


use our provided JNA always versus the system one


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

exceptions because stack traces are important for debugging


flags to configure Netty


log4j 2


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