Ummm... right. But I am using the default JRE which "points to the
recommended runtime ... openjdk-7-jre...".
With the greatest of respect, this is not a satisfactory response.
Packages in Linux repos are often behind the latest version (although
Mint is much better than many). I could probably install Java 8
(although I would have to look up how). I am unclear, however, about
what ramifications this would have for other stuff on my system. For
example, I gather installing from ppa removes openjdk.
So JabRef 3.0 has introduced a dependency which many Linux users cannot
meet without some fundamental changes. Hmmm... Not sure about the wisdom
of that.
BTW: Posting to the list as other may be interested in this topic.

Hi
I have tried updating to JabRef 3.0 on Mint Rafaela 17.2 this morning.
I get the message:
Exception in thread "main" java.lang.UnsupportedClassVersionError:

Running java -version responds with:
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3)
(7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)
I guess this is some issue that has been overlooked in the new
version?
