JabRef hangs when trying to merge entries

[erelsgl]

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

JabRef 5.0-dev--snapshot--2018-09-13--master--e83680f18
Linux 4.4.0-135-generic amd64
Java 1.8.0_181

Steps to reproduce:

1. Click on two entries
2. Right-click and choose "Merge entries".

The merge window is shown, and JabRef is frozen - it must be killed from the command line.
There are no particular log messages.

Can i look at this problem?

Thanks for your interest and for asking if this issue is still up for grabs. However, I've already a PR in the pipeline. Have a look at https://github.com/JabRef/jabref/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22 for other good issues.

Ok, how about scrollbar in preferences or dark theme?

For the dark theme issue, somebody opened already a PR. But the scrollbar issue is open. I guess the problem lies somewhere in these lines: https://github.com/JabRef/jabref/blob/master/src/main/java/org/jabref/gui/Base.css#L658-L719

Okay, I'll look at the scrollbar issue and I'll try solve this. Thank you.
