This is definitely due to a change in how classloaders work in Java after Java 8. You can refer to this thread for more information: https://community.oracle.com/thread/4011800 I spent a little time working on a patch for JabRef to use the Class.forName("foo", true, new URLClassLoader(URL[] bar)); pattern if the ClassLoader returned from the system isn't an instance of URLClassLoader, which addresses the first stacktrace reported, but there are (at least) two more that need to be addressed in the JabRef sources. So for the time-being, I recommend installing openjdk-8-jre and starting jabref like so: JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 jabref Running on Java 8, I was able to manually connect to LibreOffice using the parameters: Path to OpenOffice/LibreOffice executable: /usr/bin/libreoffice Path to OpenOffice/LibreOffice library dir: /usr/lib/libreoffice I might continue to work on a patch for this, but even the latest upstream version 4.3.1 doesn't run on Java 11 yet, so I'm reluctant to invest too much in a hack that needs to be reworked upstream.
