Jabref 5.0 dev gets stuck on 'title = {Chapter 138 - {PACAP}},'

[bernhard-kleine]

• I have tested the latest master version from http://builds.jabref.org/master/ and the problem persists

JabRef 5.0-dev--snapshot--2018-08-24--master--f43b9c7e8
Windows 7 6.1 amd64
Java 1.8.0_181

Steps to reproduce:

1. I saved (since I have not seen Jabfox functional for a while) https://doi.org/10.1016/B978-0-12-385095-9.00138-X to Zotero and exported to Biblatex format
2. the resulting bib-file could be loaded into jabref
3. however, when trying to remove the "Chapter 138 - {" jabref get stuck and can only be closed by clicking the (x) in the title bar.

I ask already in the Zotera forum to skip these nested braces. However, JabRef 5.0 should be able to deal with the deletion, in 4.1 a message appeared that the file could not be saved since braces donot match. I could after that remove the endbraces and save the file. 5.0 just stopped working.

this is almost a copy of #4256

Zotero should not skip these nested braces. These nested braces are an entirely normal way to preserve capitalization for proper names or acronyms.

This I have realized in the meantime. Then there is something fishy with Jabref dealing with deletion of an open brace. The solutuion in version 4.1 was better.

Is this error still present? If I recall this, the behaviour has been improved.

@Siedlerchr This can be closed. I tested just now and removing the first brace or the second showed a formatting error which is normal, but the program did no longer stop working. Thanks for the improvement.
