All great, but the fact remains that a complete newbie will download Apache NetBeans 11 and will probably have whatever the latest JDK is, e.g., JDK 12, will then put together a 'hello world', will then want to deploy... and then discover that an additional JDK is needed, i.e., JDK 8, to start GlassFish. I.e., a complete newbie will most likely be required to have two different JDKs -- and most likely only discover this when deploying their application. Not very nice, all this.
