I previously had Katalon for Linux working on Manjaro\Arch.
I have seen an ongoing discussion with people struggling in this forum and in the documentation where Katalon is now crashing with newer versions of Java.
Just in case this will help someone in the future, below are the steps I used to remove the current Java Environment from Arch Linux and replaces it with OpenJava version 8 (where the default was Java 16):
(1) Open Terminal.
(2) Install OpenJava 8:
sudo pacman -S jre8-openjdk jre8-openjdk-headless
(3) Uninstall the current Java Environment (*Note: make sure you check your program dependencies prior to uninstall:
sudo pacman -R jre-openjdk jre-openjdk-headless
(4) Fix your Java Environment in Arch Linux:
sudo archlinux-java fix
(5) Reboot
(6) Verify Java version in your terminal:
java -version
openjdk version “1.8.0_292”
OpenJDK Runtime Environment (build 1.8.0_292-b10)
OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)
