1. Go to WitherPanel.
2. Choose the server where you want to update the Java version.
3. In the sidebar, click on "Startup," then access the docker image field.
4. We offer all major versions of Java. Note that we will add more Java versions as required for future Minecraft releases.
5. Select the desired version, and it will be applied the next time your server starts up.

That's it! Your Java version has now been updated.

Here's a quick reference for which versions of Minecraft use which Java versions:

• Java 8 - Versions 1.12.2 and below.
• Java 11 - Versions 1.13 - 1.17.1.
• Java 17 - Versions 1.18 and above.
• Java 21 - Versions 1.20.5 and above.

We also provide custom docker images for interested users! Reach out via live chat, and we'll assist you in setting it up.

If the "Docker Image" section states This server's Docker image has been manually set by an administrator and cannot be changed through this UI., please open a support ticket, and we'll resolve it for you.
