Jabref 4.3.1 freezes and occupies much RAM

My system: Jabref 4.3.1, OpenSUSE Leap 15.0 Linux, Java OpenJDK 8 (

Jabref used to run smoothly on my computer, but since I updated to 4.3.1, it often freezes. At the moment it is frozen, and my Taskmanager says that It occupies 2.8 GB RSS and 90 % CPU. It froze when the message appeared in the left sidebar that the bib file was changed by an external program (which is not true). Is there a way to solve this?


please try again with the latest development version. This should be fixed.
It is advisable to create a backup of your bib file. https://builds.jabref.org/master/
