Description FX 2006-03-28 03:38:04 EST
Description of problem:
jabref throws up an exception just after popping up its splash screen. I don't
think it's a jabref issue since it runs fine with other javas (such as Sun and
the one in MacOS).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Download latest JabRef from
2. Run it with "java -jar Desktop/JabRef-2.0.1.jar"
Actual results:
Splash screen pops up, and then:
Exception in thread "main" java.lang.NullPointerException

   at net.sf.jabref.JabRef.openWindow (Unknown Source)
   at net.sf.jabref.JabRef.<init> (Unknown Source)
   at net.sf.jabref.JabRef.main (Unknown Source)

Expected results:
Being able to actually work through my bib files with the nice jabref interface.

Additional info:
I can provide any debugging info you think usefull if that bug turns to be
non-reproducible on your end.

In Rawhide this still fails but with a different error:

Comment 2 Thomas Fitzsimmons 2006-08-30 14:04:41 EDT
This problem is caused by one of JabRef's dependencies, Spin, using Sun-private
classes.  GNU Classpath cannot implement undocumented Sun-private classes, so
these references must be eliminated by either rewriting JabRef to not use Spin,
or rewriting Spin to only use standard classes.  Can you file a bug report to
that effect upstream with the JabRef developers?
