The Micronaut CLI is built using the Java 8 version of native image into a native executable hence the message as it is not running in a JVM.

I do think we should just remove the JVM version as it is confusing.

Yeah, that makes sense. Right now it's just inconsistent compared to the 1.3.x branch. Created #295
