• I have tested the latest master version from http://builds.jabref.org/master/ and the problem persists

Steps to reproduce:

1. java -jar JabRef-4.2.jar

I'm not able to launch jabref and the above command hang with this error:

The same command works with jabref-4.1 and I'm using jdk 1.8.0-151 on CentOS 6.9

Probably because we removed the jgoodies stuff. Try resetting your preferences, with
Or start JabRef 4.1 and swith the L&F to another except plastic and gtk
java -jar Jabref.jar -d all

You may have a bad download. Check the filesize. Happened to me the first two times I tried (right click, k to choose location). 245 kb. When I just clicked on the link and sent the file to /Downloads, the full 56 MB file arrived.

The file's SHA256 checksum is correct. The problem is indeed the Look&Feel. But java -jar Jabref.jar -d all removed all my previous setting including my customized PDF import filename pattern and I'd not recommend doing it. But changing the L&F in version 4.1 and switching back to 4.2 work. However, the L&F in 4.2 will occasionally cause the GUI to freeze and I'm switching back to 4.1 for now.

I had the same problem with. Changing
<entry key="overrideDefaultFonts" value="true"/>
to false in prefs.xml solves it.

Ok, I can reproduce it with clean preferences. When I use "NimbusLookAndFeel" and set "Override default font settings" in preferences I get java.lang.ClassCastException: java.awt.Font cannot be cast to javax.swing.plaf.FontUIResource.

java -version
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)

Platform is Linux.

Thanks for reporting, this. Fix is in progress

[Siedlerchr]

There is a version that should fix this at https://builds.jabref.org/removeGTK/ Please try it out.

Ok, it seems to be working now. However, "GTKLookAndFeel" is still visible as the default one.
