Jabref freezes when dragging entries to groups panel or moving entries within groups

[juejung]

JabRef version 4-beta2 on Ubuntu 16.04 with open JDK 1.8.0_131 (happens also under Windows 7)

Steps to reproduce:

Issue A:

1. Drag new entry into a group
2. Jabref freezes - need to kill process to continue

Workaround: Assign a new entry to a group by using right-click context menu -> add to group
This will add an article to the assigned group.

Issue B:

1. Drag an entry in the groups menu into a different position
2. Jabref freezes - need to kill process to continue

Workaround: None found yet.

I can confirm both issue A (dragging an item/article to a group) and issue B (dragging a group to a new position in the groups panel) on:

JabRef 4.0-dev--snapshot--2017-07-19--master--2f12fecfb
Windows 10 10.0 amd64
Java 1.8.0_141

The available snapshot 2017-07-25--master--0847f5d15.exe does not solve this. Where to get the files?

Thank you for reporting this issue. We think, that is already fixed in our development version and consequently the change will be included in the next release.

We would like to ask you to use a development build from https://builds.jabref.org/master and report back if it works for you.
