Steps to reproduce:

1. Create new BibTeX/BibLaTeX database
2. Create a group
3. Check "Dynamically group entries by searching a field for a keyword" and "regular expression" and fill Name and Keyword
4. Double click the group name or select "Edit group" in the context menu

Thanks for your very detailed and clear report.
This should be fixed now in the latest development version. Could you please check the build from http://builds.jabref.org/master/ and report back if it's still not working. Thanks!

I tried to run java -jar JabRef-3.8.2-dev--snapshot--2017-01-26--master--ed89bdae2.jar and got Error: Invalid or corrupt jarfile

We had some problems with our build server. Should work now.
