I've done this before with no problems but that was back in 2016!
Running Fedora 27 with $ java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)
When I try running I get:
java -jar ./HyperCon.jar
UpdateCheck: There is a no new version available
Exception in thread "main" java.awt.HeadlessException

Only doing this cos my Pi with the LEDs is running on Openelec 6 and I want to move it to LibreElec to match the rest of my installations ... along with the fact that the Pi suddenly started locking up - seemed to coincide with an Openelec update when I rebooted the Pi. Pi is standalone driving the LEDs with an HTPC providing the signals via the Kodi addon.
