JabRef version 5.1--2020-05-13--98b62ba on Ubuntu 18.04.4 Linux 4.15.0-99-generic amd64 (Java 14.0.1)

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

I installed the latest dev version because it fixed another bug I was having (see https://discourse.jabref.org/t/scrolling-by-typing-a-name-does-not-work-in-5-x/1989). This bug is fixed but I noticed I cannot connect to LibreOffice anymore, while it was working just fine with my previous version (5.0–2020-03-06–2e6f433).

Steps to reproduce the behavior:

1. Open a LibreOffice document, and the LibreOffice/OpenOffice connection panel in JabRef.
2. Click "connect" (clicking on "manual connect" gives the same thing, and the path is correct).
3. While the connection was almost immediate on the previous version, now it gets stuck on a window "Autodetecting paths..." until I hit cancel. I have not managed to get a libreoffice connection working.
