Has any core dev of Processing thought about this? Would this affect Processing? Would it be possible to switch to OpenJDK? (Last time I tried, it did not work well if I remember, but that was a while ago).
Update: My bad, this article is a bit misleading. There still exists open source GNU GPL Java11 JDK available at this address: JDK 11 Releases. The article says Oracle released a commercial JDK with the restrictions mentioned above and people might be confused between the two.
These things are good to be aware of, although I don’t think Processing is in any danger of migrating to Java 11 anytime soon.
Processing 3 uses Java 8 (but does not support all Java 8 language features). […] there are no plans to support Java 9 or 10. The first version we might use is Java 11, a “long term support” release, scheduled for September 2018. However, without anyone contributing their time to rework the code for Java 9/10/11, we’ll be using Java 8 for the foreseeable future. Supported Platforms · processing/processing Wiki · GitHub
Write now Processing syntax supports most of 7 and some 8 language features running backed by 8.
Well at least there’s now no choice but for Processing to be a fully FLOSS project and use OpenJDK! I would assume the best option will be AdoptOpenJDK though. Oracle are not releasing a free LTS.
Shipping Oracle Java 8 after Jan 2019 might be more difficult. A switch to OpenJDK 8 first might be good.
