When saving: The libary has been modified by another program

Edit: JabRef 5.0, 5.1, 5.2, 5.4 till current version (Nov2021) is affected.

If you add a comment please add

• your operating system
• encoding of the document (e.g. ASCII, ANSI, ISO-8859, UTF-16 , …)
• the line-seperators used in the file (lineforward or cariage-return or both or mixed)
• the settings of Options > Preferences > File – (a) Newline seperator (try LineForward) – (b) Always reformat BIB file on save and export (try disabling) – © Autosave local libraries (try disabling)

Original post

JabRef 5.0-dev--snapshot--2019-04-09--master--0dd091f31
Linux 4.15.0-47-generic amd64 
Java 1.8.0_201

Ubuntu 18.04

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

Steps to reproduce the behavior: (same as #4810 )

1. open .bib-file
2. press “ctrl” & “s”
3. Repeat step 2 till Bug appears.
4. The message “The library has been modified by another program” appears
5. DO NOT accept the changes, otherwise all entries will be doubled (click dismiss)

I’m still seeing this issue, even after deleting these shared backup files from the bibtex shared Dropbox folder and starting JabRef on a clean directory:

Here’s a video of current behaviour:

We should remove the sav and bak feature. This is so 2000. I forced to keep it in 2015, but I regret it now. Version control and backup feature are now common things.

Maybe, if we just remove bak and sav (and directly save to bib), all these change detection issues could be resolved.
