[dkczk]

JabRef version

5.10 (latest release)

Operating system

macOS

Details on version and operating system

macOS 12.6

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

1. I add some articles to my new library
2. CMD + S to save the library
3. The following error is returned:

Are you saving your library by chance in a sync folder like Google Drive or on a smb network share? I found this bug report https://bugs.openjdk.org/browse/JDK-8167023

[dkczk]

Yes, I want to save the file to a network drive as my whole thesis is saved there.

[Siedlerchr]

Thanks, maybe we can add a check for that file locking mechanism and still provide an option to save the file. In the meantime you have to save your bib file to a different location

[Siedlerchr]

@dkczk I've implemented a workaround. Can you test if this version works for you as well? https://builds.jabref.org/pull/10454/merge

(Tested it with macOS and a windows network share over smb)
