BEA-2165021 ResourceManagement is not enabled in this JVM

Starting WLS 12.2.1 with a JDK 8 I get this INFO message:

<Info> <RCM> <BEA-2165021> <"ResourceManagement" is not enabled in this JVM. Enable "ResourceManagement" to use the WebLogic Server "Resource Consumption Management" feature. To enable "ResourceManagement", you must specify the following JVM options in the WebLogic Server instance in which the JVM runs: -XX:+UnlockCommercialFeatures -XX:+ResourceManagement.>

here https://docs.oracle.com/javase/8/docs/technotes/tools/enhancements-8.html they say "##The options -XX:+ResourceManagement and -XX:ResourceManagementSampleInterval=value have been added. Resource Management is a commercial feature."

I think this has nothing to do with the try-with-resources clause.

Euphemistically speaking, there doesn't seem to be lot of documentation on this -XX:+ResourceManagement flag...
