It is commendable that JDG image reports the configuration results at the start of the image but it reports valid configurations as errors, en example is

WARNING! Neither SSL_KEYSTORE_PATH nor HTTPS_KEYSTORE is set. HotRod SSL will not be configured.
WARNING! Neither SSL_KEYSTORE_PASSWORD nor HTTPS_PASSWORD is set. HotRod SSL will not be configured.

But if basic template is used (no SSL) then this should not be warning.

I propose to change to format to report configuration summary and keep WARNING keyword only to real misconfigurations - like haveing USERNAME but not PASSWORD etc.
