download-jdk VS openJDK-docker

There are plenty of vendors providing builds of OpenJDK free to use in production including Oracle themselves. Oracle's build of OpenJDK that is free to use in production is found here: https://jdk.java.net.

Java can also be found in OpenJDK. Download your version, extract it (usually, the default directory is /usr/lib/jvm), and point the java program.

As someone else has mentioned, Oracle JDK still has limitations when used in commercial applications. However, there are lots of JDKs that are free to use for anything you want to do with it. jdk.java.net is where I used to get mine from. If you want an installer adoptium.net is also great (that's the JDK provided by the Eclipse foundation).

Java.com is the website for the product Java. Oracle owns java as mentioned in 1 so it makes sense they would have java-related things on their website. jdk.java.net is the domain for the Oracle OpenJDK

This, the oracle JDK from oracle.com.. Not the Oracle build of the JDK from http://jdk.java.net/ which has always been free.

https://jdk.java.net/ is probably the most standard as those are the build from openjdk itself. The eclipse temurn is a different Openjdk build by a different organization.

OpenJDK is an open-source project. The key word there is 'source'. OpenJDK does not provide binary distributions. Yes, there is one available from jdk.java.net but that is the Oracle OpenJDK JDK.

Install OpenJDK and Java Runtime Environment (JRE) 11

Reloading is nothing new under the sun for Lisp, I believe. For ML and adequate reload-ability, one might be hard pressed, but it's nothing new under the Sun (hint, hint). Maybe too on the nose, but one probably wants good inlining, and thus more "speculative" de/optimisation to preserve redefinition.

If they don't want Oracle's Java, why can't they use a subset of OpenJDK (licensing noob here)?

I think they use a circular queue of functions that is each executed for around 100 ms. I am guessing the system timer is used to generate an interrupt that pauses execution of the current function and starts executing the next function. Apple's Java code is probably closed source. I did find mention of an openjdk here: https://openjdk.java.net. I haven't looked at the source code yet.
