As mentioned here. Using version 11 of javafx causes conflict with Wayland in Ubuntu 18.04 and above. Consequently, it also led to errors in students using WSLg since most WSL users by default uses a version of ubuntu. This can be fixed by bumping javafx version to 11.0.2 from 11.
Besides bumping to 11.0.2, it is probably also better to include /hs_err_pid[0-9]*.log in the .gitignore to avoid pushing log files to the repo for potential future errors.
