I promised to configure a laptop to a friend of mine, who needed to run one Java-based application on it. Little did I know, what I had promised. My idea was to install Ubuntu 18.04 and OpenJDK and be done with it.
When my plan was implemented in reality and it was time for the first test, I noticed there was only a big white window on the screen. We decided to RTFM and found the instructions. They recommended using Windows XP and Oracle's Java.
