Amazon offers an open jdk for Windows (and other OS), but just for Java 8, 11 and 16. You can download it from here: https://aws.amazon.com/es/corretto/

After installing it and running the java -version command, you will see something like this:

>java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment Corretto-8.242.08.1 (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM Corretto-8.242.08.1 (build 25.242-b08, mixed mode)

Do you think it is right to assume that Java 8 will never go away?
On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge. If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options: Limiting your involvement with Reddit, or Temporarily refraining from using Reddit Cancelling your subscription of Reddit Premium as a way to voice your protest.

When I go to download Java from Oracle it's Java 8
The latest released version is 20. See our section "Where should I download Java?" on the sidebar for some links to OpenJDK distributions. Oracle changed their licensing of their own JDK a while ago, so Java 8 is the last one you can really freely use from Oracle if I am not mistaken. Just use one of the OpenJDK ones, they are essentially the same. More on reddit.com

In August 2019, OpenLogic recognized that the current state of Java WebStart technology in OpenJDK was not as capable as the Oracle JDK equivalent. The build was missing critical functionality such as site exceptions, jar key matching, Windows Proxy settings, and other functions. OpenLogic added functionality to IcedTea-Web to bring parity with Oracleโ€™s WebStart distribution. These upgrades were accepted into IcedTea-Web 2.0. OpenLogic now provides free, quarterly builds of OpenJDK 8, OpenJDK 11, OpenJDK 17, and OpenJDK 21 for Linux, Windows, and MacOS.

r/Minecraft on Reddit: Where can I download Java 8?
July 17, 2021 -

I want to use forge for 1.16.5 since the mods I really want are only on that version, and I can just mod in 1.17 stuff. I'm on a new laptop, and it didn't have any Java stuff installed. I installed the latest version of Java fine, but it turns out it was the wrong one for what I needed and only works with Forge 1.17.1 and 1.17.1 JAR files.

I found the link to get the Java SE Development Kit 8 Download, but this time it's asking me to log in to do it. Alright, sure, not that big a deal, I'll make an account.

The problem is, to make an Oracle account I apparently need to give them my work information?! Never mind that I'm a stay-at-home spouse so I couldn't even if I wanted to. I'm certainly not giving them my personal home info. Here's the create an account page so you can see exactly what I mean. It's all required info to create an account.

Is there a way to create an account without all this nonsense? Or possibly somewhere else I can download Java 8?

EDIT: Bonus question--of all the available mods for backporting 1.17 stuff, are there any specific ones y'all would recommend? I've found, like, five.
