Group information not saved in a Postgres db

[g-mos]

JabRef version JabRef-4.0.0-dev on Ubuntu 16.04

Steps to reproduce:

1. Opened a Postegres literature db
2. Created some groups
3. Closed and reopend the db. The groups have disappered

When #2284 is fixed, this should be fixed, too.

I have the same problem with

JabRef 4.0.0-dev--snapshot--2017-06-09--master--b5f1e7d7e
Windows 7 6.1 amd64
Java 1.8.0_66

Thanks for any help! I use the groups frequently and really need them to work. I've switched to the latest snapshot due to Bug #2898. I'm really stuck because I need both groups and DOIs to work! Thanks for any help.

#2284 says that this has been fixed, so I am closing this issue.
