Java Version Selection
On April 4th 2022 we rolled out our Java Version Startup Parameter to all non-proxy Minecraft servers. This allows you to select the version of java your server runs using a drop down located on the Configuration → Startup Parameters page.

In order to use the selector, all you need to do is navigate to the 
Startup Parameters page and select the Java Version you need from the drop down. After selecting it, you just need to start or restart you server to see the changes made to your container.
When selecting a Java Version, refer to the table found on the right to find the correct version of Java for the version of Minecraft you’re running.
Some plugins/mods may require that you use a newer version of Java, so don’t be worried if, for example, your server asks that you use Java 17 on a 1.16.5 server.
| Minecraft Version | Java Version |
|---|---|
| 1.8 to 1.11 | Java 8 |
| 1.12 to 1.16 | Java 11 |
| 1.17/1.16.5 | Java 16 |
| 1.18 to 1.19.4 | Java 17 |
On December 2, 2020 - PaperMC released two announcements regarding the Minecraft 1.17 release and the push to require the usage of Java 11. This requirement has been updated to Java 16 on May 12, 2021 as new details regarding Minecraft 1.17 were released for June 8th.
Our Team at WinterNode works with our Community Members to keep updated with important changes.
After paper build 1.16.4 #311, you will see the following warning as by default, since we originally ran containers using Java 8/Java 11 by default.
Please follow the Java Version Selector guide to get rid of this pesky message.
