Batmass does not run under Ubuntu 18.04 with JDK 12 #17

I installed BatMass v0.3.1 under Ubuntu 18.04 with the install script batmass-linux.sh. I've installed JDK 12. When I start the application the BatMass logo is shown in the center of the screen. But the application does not start.

Batmass hasn't been updated to run with new versions of Java and there have been a lot of potentially breaking changes since Java 8. I should have included a JRE with BatMass installer originally, but I didn't know how to do it back then when it was released.

Now if you still want to run BatMass, there's a rather easy way without messing with your system's main java install.

There's a config file <batmass-install-dir>/etc/batmass.conf which has the following line in it commented out by default:

#jdkhome="/path/to/jdk"

Even though the name is jdkhome, it can actually point to a JRE. You can download A JDK or JRE version 8 for example from here: https://adoptopenjdk.net/releases.html. Don't download an installer, just a zip file. Unpack it anywhere and point jdkhome variable to it. On windows use double slashes in the path, like so:

# OpenJDK 8 - works
jdkhome="C:\\tmp\\OpenJDK8U-jre_x64_windows_hotspot_8u222b10\\jdk8u222-b10-jre"
# OpenJDK 10 - doesn't work
#jdkhome="C:\\tmp\\OpenJDK10U-jre_x64_windows_hotspot_10.0.2_13\\jdk-10.0.2+13-jre"
