Jabref: Menu View on empty file => Uncaught exception

[mlep]

JabRef 5.1--2020-05-04--b5599c9
Linux 4.9.0-12-amd64 amd64
Java 14.0.1

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

When clicking on the menu item "View" with an empty library on focus, a message "Uncaught exception" is displayed.

Steps to reproduce the behavior:

1. Create a new BibTeX library
2. Click on menu View

A window pops-up, displaying the message "Uncaught exception occurred in Thread[JavaFX Application Thread,5,main]
Afterwards, To be able to display the menu View on another file, JabRef needs to be re-opened.

Note: All the other menus are working as expected.

Funny coincidence, I recently discovered the bug as well and was already working on a fix (I just did not create an issue)
Refs #6402

[mlep]

And before creating it, I looked only in the list of issues... :wink:
Well, now the PR has a corresponding issue!

[Siedlerchr]

Should be fixed in master now. Just merged

[mlep]

I confirm this is fixed in:
JabRef 5.1--2020-05-22--ef2a31c
Linux 4.9.0-12-amd64 amd64
Java 14.0.1

Thank you for the work.
