Quite some bugs reported against JabRef are actually problems with the used
Java Virtual machine.

Before filing a bug against JabRef please make sure to test with all
installed JVMs, and provide the output of the jabref wrapper called with the
debug parameter in the bug report, e.g.:

$ DEBUG_WRAPPER=1 JAVA_HOME=/usr/lib/jvm/java-6-openjdk/ jabref
$ DEBUG_WRAPPER=1 JAVA_HOME=/usr/lib/jvm/java-6-sun jabref

Please also go through the bug reports against the JVM you're using at
http://bugs.debian.org/ and check if similar problems are already reported
there.
