To be fair, the relevant quote from that article (and from the terms) is:
> You may not: use the Programs for any data processing or any commercial, production, or internal business purposes other than developing, testing, prototyping, and demonstrating your Application;
Which seems to suggest that you can use the Oracle JDK to develop, test, prototype, and demonstrate your application, even in a commercial setting. You just can't run Oracle JDK in production without a license. But IANAL.
As for the JRE, I haven't really kept up. I'm not sure if there will be a separate Oracle JRE11 and what its license terms will be. Right now, only JDK11 is posted for download.
