java.lang.IndexOutOfBoundsException after creating new library and new group

[ThiloteE]

JabRef version

Latest development branch build (please note build date below)

Operating system

Windows

Details on version and operating system

Windows 10 21H1

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

JabRef 5.4--2021-11-07--d11ba36
Windows 10 10.0 amd64
Java 16.0.2
JavaFX 17.0.1+1

How to reproduce:

1. Open library (1) with a number of entries
2. create new library (2)
3. copy some of the entries from (1) to (2).
4. Save and close library (1)
5. Add subgroup to library (2)

Four Errormessages emerged. I attached the first 3 of them.

Edit: i can't reproduce with the above steps, but this is kinda what i did. There must be an additional condition. Sorry!
