Sorry to hear that you have problems with JabRef, and thanks for this excellent bug report! First of all, I'm unfortunately unable to reproduce it, JabRef still works fine for me, with OpenJDK 8. Therefore I'm lowering the severity of the bug. > 1.

The log4j warnings are harmless; there are there since forever, and I also get them before JabRef starts successfully. > 4. When trying to file a bug report I got the info Yay!

Ha! Here's an extra line, and that's the difference to my output. Now we just need to find out what's missing / different on your system, so that java can't connect to the X server. (But then, your test with OpenJDK 7 should work?) Do other java programs work for you? Which window manager are you using? I'm cc'ing the java team's mailing list, maybe someone has an idea there. > 9.
