Missing dependency java-6-openjdk

[mantaraya]

Binary package hint: jabref

I have the sun-java-jdk installed, but jabref doesn't start:

$ jabref

ERROR while starting or running JabRef:

----------------
If I install openjdk-jre (i had openjdk-jre-headless installed), jabref runs fine. Maybe this is an issue arising from my upgrade from 9.10?

mantaraya,
Java programs that create a GUI on the screen will not run with openjdk-6-jre-headless, because this package is intended for servers without a screen. Thus, jabref requires openjdk-6-jre to run.
When starting a Java application that should run headless, I think you are required to pass it the parameter -Djava.awt.headless=true and then it will not try to load/bind libmawt.so

Sun Java no longer exists. Please open a new issue if it is still a problem on an up-to-date installation.
