A few months ago, I received a Java update message with a commercial use licensing message. Starting January 2019, Oracle no longer issues public updates for commercial users of Java SE 8, ending free updates for commercial use. Oracle has moved Java SE to a subscription-based licensing model. The Oracle Java license changed for releases starting April 16, 2019.
At the time, I was using Oracle JDK (Java SE Development Kit) 8 to develop proprietary software for my business, Heaven's Disciples. However, Oracle does provide OpenJDK, which is free to use under the Open Source (GPLv2+CE) license.
Various organizations and companies provide OpenJDK builds and binary distributions, including AdoptOpenJDK, Amazon Corretto, Azul Zulu Community, BellSoft Liberica JDK, IBM OpenJDK, jClarity, Red Hat OpenJDK, SAP SapMachine, and others.
I have chosen to go with Zulu Community, an OpenJDK build by Azul Systems that is TCK-tested and free to download and use without restrictions.
I plan on installing OpenJFX, the free version of JavaFX, through the Zulu Community downloads as well.
After installing OpenJDK 12, I was able to run my proprietary Java software programs, including World Engine, a Space Engine planetary system editor.
