JabRef version

Latest development branch build (please note build date below)

Operating system

Windows

Details on version and operating system

Windows 11 23H2

Checked with the latest development build (copy version output from About dialog)

• 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

Hello there :)

1. Select entries in your library (5 are enough).
2. Run the "Cleanup Entries" feature.
3. In my case I wanted to get rid of the field Urldate, which means that I take away every tick on the checkboxes and only enable field formatters.
4. I add: "Field name: Urldate" and "Formatter name: Clear"
5. I hit enter.

A window ("Exception details") should show up and say: "Unhandles exception occured."
When looking at the details a bunch of java related stuff comes up, but I can't read computer language very well. But every line of this text ends with the words "Unknown Source" within brackets.

When looking at the entries selected only one was cleaned up.
After installing the latest development version I was able to clean up two entries but the process still breaks in the same way.

What can I do to fix this? Or is it an issue that has to be fixed by the developers and I have to wait?

Thanks in advance
Luram
