Java Minecraft

Does anyone know currently on 26.2 how to get Java Minecraft sideloaded? I know Pojav is discontinued for amethyst launcher but as far as I know it does not come compiled with Java runtime, and you can’t even load into a world without a crash and log. Basically what I am asking is how to get the Java runtimes compiled with amethyst launcher. Trying to do this in LiveContainer. Appreciate any help!
