Java 11 won't launch, but Java 8 will?

So, when I install Linux Debian (64-bit), and get Minecraft, I need to install Java 8 because Java 11 won't launch the game for some reason. Java 8 works, with frame stutters every now and again, but that isn't my problem. My problem is that I use a client called Labymod for the game, that uses Discord Rich Presence, but with Java 8, Minecraft won't show up in "Game Activity", and when I click "Add it!", I don't see a minecraft option, but a java option does appear. I know Java 11 will work, because with Java 11 discord detects minecraft opening for a split-second, and it shows up as just played. I want to use my Labymod rich presence, so is there a fix for this?
