No-GUI mode (--nogui) should not try to use DISPLAY #7510
Description
This has already been reported in #3754, but is apparently not fixed.
I can reproduce the failure for JabRef versions 4.0, 4.3.1, 5.0, 5.1, 5.2 and current 5.3--2021-03-09--5855bcf on Ubuntu 16.04 (openjdk version "1.8.0_282", openjfx 8u60-b27-4). It works in old JabRef 3.8.2.
Steps to reproduce the behavior:
- Switch to non-graphical TTY1
bin/JabRef -n --version
