As far as I can see from the error message the application is a Java program
so it shouldn't be that difficult to have it running on Fedora. But I'm too
bad with deb files and I can't simply extract its content in order to exam it.
If you know how I can inspect it/extract its content I will investigate a
little more in this direction.

.deb files are ar archives containing .tar.gz files, so it is easy enough to 
unpack on Fedora.  See:
https://unix.stackexchange.com/questions/138188/easily-unpack-deb-edit-postinst-and-repack-deb

If you have trouble get it to run, grab an Ubuntu 18.04 "live" iso, create a bootable 
USB (I use the Fedora tool), and boot into the live distro, and install the .deb 
package for further study (but note that the install will be lost when you reboot).
