Starting from February 2019, Oracle JDK updates will require Commercial license if you make any business using Java (eg, you're a Java Developper not spending only your spare time developping with Java).

It includes Java not only on your server, but on your laptop as well.

What's nasty is Java versions will remains free to download since if you use it as an individual/personal use, you won't be concerned by the commercial aspects of the license.
