Considering use of Amazon Corretto, the new openjdk jvm, especially with ColdFusion

As I posted earlier today, there are big changes afoot in the Java world, about commercial/production use of Java going forward. For my readers (mostly ColdFusion users), this is big news, as it is for anyone using Java for commercial (or in Java 11, even production) purposes.

But here's some good news: Amazon has recently released a new free JVM (java virtual machine) implementation based on the OpenJDK specification, called Corretto. In this post, I want to share some news about it. (Off the bat, let me tell my friends on any Linux flavor other than Amazon Linux 2, this is not yet available to you. For now it is only available for Amazon Linux 2 as well as Windows, MacOS, and as a docker image. Other Linux flavors are due in Q1 2019.)

For much more, read on.

What's a CF shop to do: Oracle's changed stance on commercial/prod use of Java, going forward?

(While this topic is written toward ColdFusion users, much of the information will apply to readers running ANY Java app/app server for commercial/production use, whether Java 8, 9, 10, or 11.)

Did you know that Oracle will no longer offer free updates/security patches for Java 8, if Java is used for commercial purposes beyond Jan 2019? After that, you must pay them for support/updates (including security updates). And did you know that they are not offering their next "long-term" release, Java 11, free for PRODUCTION use at all (and that you must obtain a separate license)? Finally, while Oracle will be offering a free openJDK implementation, did you know they will only be committing to supporting/updating it for 6 months after release, leaving subsequent updates to the community of contributors?

These are important changes for those running CF, since it runs on Java. (CF2016, 11, and 10 run on Java 8. And while CF2018 came out on Java 10, that Java release will not last for long, yet another complication/curiosity that I wrote about back in May: On ColdFusion and its support for Java 9, 10, and 11.)

For now, while Adobe is aware of the issue of the pending Oracle licensing change, they have yet to clarify things on the matter (at this writing, Nov 15 2018).

While we await that news from them, I wanted to share this news here to help my readers, as well as a bit more below for those wondering about the matter, and options going forward.
