The following error will happen when you start the server and it tries to use an incorrect Java version.

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

To fix this with your ExtraVM Minecraft server, you will just need to rename your existing server .jar file. If you're using Forge 1.12.2 or 1.16.5 rename your server .jar file to "forge.jar" in both the control panel JAR File text field and in the FTP or file manager. This will force it to use Java 8 at startup. If you use Forge 1.18.1, please refer to our Forge 1.18.1 setup guide here.
