1. In section Table 4.1. JVM Environment Variables

https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/8-beta/html-single/using_jboss_eap_on_openshift_container_platform/index#ref_jvm-environment-variables_assembly_configuring-the-jvm-to-run-your-eap-application

There sentence can be removed in my opinion

In addition, if automatic memory calculation is not enabled, the inital Java memory (-Xms) and maximum Java memory (-Xmx) are not defined.

It is lefover from previous state where -Xms -Xmx were computed. E.g. discussed here https://issues.redhat.com/browse/JBEAP-23893 This in not true anymore inEAP8 images.

2. This whole section 4.3. Resource limits in default settings can be removed https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/8-beta/html-single/using_jboss_eap_on_openshift_container_platform/index#con_jvm-resource-limits-in-default-settings_assembly_configuring-the-jvm-to-run-your-eap-application

This changed by https://issues.redhat.com/browse/OPENJDK-630 and those options are not added anymore.
