I am part of a FIRST robotics team and we purchased an JTX1. I have been trying to run a .jar file to no avail. We are using oracle java 8, installed using sudo apt install oracle-java8-installer. Java is installed, the help page is present, and the command java -version returns our current version 1.8.0_121. When running java -jar filename is always throws and exception in thread “main” but the exception changes based on the jar we try to run. We have tested the jars successfully on other computers.
