I tried to add an entry by DOI.  
10.3109/17483107.2014.961179

JabRef 3.8 told me the “URL is invalid” but doesn’t show me the URL. 😃

There is a known issue with CrossRef that is fixed in the most recent development version of JabRef.

Hi!

Just to make sure: Tobias was talking about the most recent **development** version of JabRef - which is available at [https://builds.jabref.org/master](https://builds.jabref.org/master) - or you can use the beta release here: [https://github.com/JabRef/jabref/releases/tag/v4.0-beta3](https://github.com/JabRef/jabref/releases/tag/v4.0-beta3). These versions should work - the newest stable release version 3.8.2 is broken in this regard.
