Drag and drop from one grop to another freezes Jabref

[dfioravanti]

JabRef version 4.0-beta2 on Ubuntu 17.04 with both openjdk and oracle JVM

Steps to reproduce:

1. Add entry to a group
2. Try to drag and drop to another group
3. Jabref freezes without anything been outputted on stdout

I would like to add the event log but is impossible since Jabref freezes completely and even if I lunch it from terminal nothing is printed. Is just completely unresponsive until killed

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.

It works, thanks. Sorry for the duplicate, I looked before submitting somehow I missed that it was already closed.
