I installed: Liberica Standard JDK 8u282+8 ARM 64 bit for Linux
from: https://download.bell-sw.com/java/8u282+8/bellsoft-jdk8u282+8-linux-aarch64.deb
I will admit I am a little out of my element here. Do I have to tell the launcher to use this particular install of Java? As far as I can tell this is the only one I have installed.
