download-jdk VS temurin17-binaries

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.

ok so it looks like java 17 isn't in the package manager, so you will have to download it, and install it manually. First you have to download the correct version of java (which you already did), wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_arm_linux_hotspot_17.0.1_12.tar.gz Then you can make a directory for your java installation, sudo mkdir /opt/jdk Then you need to extract it to the folder you just made, sudo tar xzfv OpenJDK17U-jdk_arm_linux_hotspot_17.0.1_12.tar.gz -C /opt/jdk

wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_arm_linux_hotspot_17.0.1_12.tar.gz tar xzfv OpenJDK17U-jdk_arm_linux_hotspot_17.0.1_12.tar.gz ./jdk-17.0.1+12/bin/java -version

wget -O jdk.tar.gz https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz tar -xzf jdk.tar.gz -C jdk_home JAVA_HOME="$(pwd)/jdk_home" $JAVA_HOME/bin/java.exe -jar project.jar

Are they just bundling a JRE? At least from what I've seen in other flatpak manifests, many will just pull the latest binaries from adoptium (formerly adopt open jdk) (here)[https://github.com/adoptium/temurin8-binaries] and (here)[https://github.com/adoptium/temurin17-binaries]. I think you could also specify the runtime from flathub.
