Hello I'm new, never played Wurm, never tried to fiddle with Java. I understand you're using the Java Network Launching Protocol (JNLP) to launch your Java Web Start application. It seems the most natural way to do this is by using JavaWS.
The following error occurs during the launch process:
net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report.

I'm on Solus. Also got the non-open oracle java version (JRE 8u172) installed.
edit: from looking at the Java Console details it seems as if both packages are being used, the oracle java and the open implementation (openjdk-8). I'd rather have the open version installed and oracle java removed, if possible. Does it work with both?
