Won't launch on Java SE 11.x.x

[adakac]

The following error gets returned, seems like Java 11 doesn't support the Substance UI-Theme. My Java Version:

java version "11.0.2" 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

Error Output on java -jar .\advancedyoutubedownload.jar:

Can you test whether this is definitely an issue with the java version by switching to an older java version manually and re-testing?

If it is, I guess the easiest way is to remove the look and feel.
