[Android Apps and Games] madmack:
Need help. I'm desperate to get this to work on arch linux.

This is the log file I'm receiving now. I tried running this with multiple JRE/JDK's (OpenJDK and Oracle's) and I get the same error. The following snippet is from the latest Sun's JDK 11.

Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "main"

I'm trying to run with command

java -Xss256k -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dfile.encoding="UTF-8" -jar BubbleUPnPServerLauncher.jar

Any help or pointers would be appreciated. It used to work just fine! I tried JDK 8 and 7 as well to no avail.

Edit: same thing with JDK8 (Oracle's).
