Uncaught Exception when importing a library which is currently open on JabRef

[CaptainDaVinci]

JabRef unknown
Linux 4.14.79-1-lts amd64
Java 1.8.0_192

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

Steps to reproduce the behavior:

1. Open a library with one or more entries
2. Import the same library

Should be fixed once #4692 is merged

[tobiasdiez]

This should be fixed in the latest development version. Could you please check the build from http://builds.jabref.org/master/. Thanks! Please remember to make a backup of your library before trying-out this version.
