Did you install the package which provides libswt-gtk*.so libraries?
from docker-baseimage-gui.

Yeah, my Dockerfile looks like:
FROM jlesage/baseimage-gui:ubuntu-18.04
# Install xterm.
RUN apt-get update && apt-get install -y openjdk-8-jre libswt-gtk*
# Copy the start script.
COPY nitro.jar /app/
COPY startapp.sh /startapp.sh
# Set the name of the application.
ENV APP_NAME="Nitroexplorer"
from docker-baseimage-gui.

Maybe you could try to install it on a normal Linux installation to see how the app is started. They are often started with a couple of java options...

I'm having a similar problem: I'm getting errors related to /dev/null as well. I'm trying to make an image that loads Eclair GUI, and (part of) the traceback is the following:

As we can see, it also uses /dev/null as a directory. I'm currently trying on the ubuntu-18.04 tag with openjdk-11, but also tried debian-9 and manually downloading openjdk-11 from AdoptOpenJDK.
I tried running the JAR on a Docker container with Lubuntu + VNC and started correctly with no errors.
So, It might have something to do with some Java option, maybe is trying to write on the /home directory and by some reason it defaults it to /dev/null? Kinda weird.

@calgara12 The problem seems to be that this image uses a user with no HOME route (more like the home set to /dev/null), which causes these errors (check this: https://github.com/jlesage/docker-baseimage-gui#home-environment-variable).
Theorically we can set the home in Java like this (here I show my startapp.sh file):
#!/bin/sh
set -ex
HOME="/tmp"
_JAVA_OPTIONS="-Duser.home=${HOME}" exec java -verbose -jar /eclair.jar
In my case another errors show up, but at least is not showing problems related with /dev/null. Maybe it works for you.
(Haven't tried yet setting the HOME env var before running the java command)

similar here: The Application is using eclipse and trys to write to /dev/null/.eclipse...
I tried changing Home to /config but no luck. Any Ideas how I can make him not using /dev/null?

For openjfx cache, I had same issue. This option fixes it...
-Djavafx.cachedir=/tmp
from docker-baseimage-gui.

java -jar \
-Djavafx.cachedir=/tmp \
-Duser.home=/tmp \
This should fix your issues
