[Vladimir Petko]

Sample project:
https://github.com/beryx-gist/badass-jlink-example

clone it and produce a jlink image with

`./gradlew jlink`

the image uses 300+ mb

This is caused by https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/574997

Temurin build of openjdk uses --with-native-debug-symbols=none.

I have validated jmap with openjdk-11 and can confirm that jmap works when the jdk is compiled with the setting above.
