JabRef forgets opened libraries

[mlep]

JabRef version

Latest development branch build (please note build date below)

Operating system

GNU / Linux

Details on version and operating system

JabRef 5.8--2022-09-29--fca9fb9 Linux 5.10.0-18-amd64 amd64 Java 18.0.2.1 JavaFX 19+11

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. open a (pre-existing) library (e.g. https://github.com/JabRef/jabref/blob/main/src/test/resources/testbib/jabref-authors.bib)
2. create a new library (e.g. File -> New library)
3. edit a bit this new library (e.g. add/paste an entry)
4. close JabRef (e.g. File -> Quit)
   At this point, a window entitled "Save before closing" is displayed.
5. select Discard changes
   JabRef closes
6. open JabRef
   Bug: No library is displayed, while the pre-existing one (e.g. jabref-authors.bib) should be.

Hi, I'm a new contributor. I would like to try solving this. Could you assign me this issue?

[ThiloteE]

hey, you can try of course.

Seeing as you are pretty new to GitHub, I assume you are new to programming. For newcomers we have assigned issues with the tag "good first issues". Good first issues from Koppor also count. If you get stuck here, I would suggest to try from there. If you are a student, the "candidates for university projects" page also offers some issues of varying difficulty and scope and that have been estimated to be compatible with university courses as well and often bring a larger feature to JabRef.

As a general advice: check out https://github.com/JabRef/jabref/blob/main/CONTRIBUTING.md for a start. Also, https://devdocs.jabref.org/getting-into-the-code/guidelines-for-setting-up-a-local-workspace is worth having a look at. Feel free to ask if you have any questions here on GitHub or also at JabRef's Gitter chat.

Try to open a (draft) pull request early on, so that people can see you are working on the issue and so that they can see the direction the pull request is heading towards (but do testing in your local environment). This way, you will likely receive valuable feedback.

Formulated differently, the request is some Notepad++ behavior

JabRef should remember all newly, but unsaved libraries.

[koppor]

In JabRef, the unsaved libraries are not restored upon restart

Additionally, JabRef forgets all opened libraries:

1. Closing
   
2. After restart
