Could confirm this under windows, too:

1. Create a new biblatex library
2. Paste a doi
3. Double click to open the entry editor

[AEgit]

JabRef 5.0.0-dev--2019-10-14----d2ddff574
Windows 10 10.0 amd64
Java 12.0.2

I can confirm this issue as well.

This should be fixed in the latest development version. Could you please check the build from http://builds.jabref.org/master/. Thanks! Please remember to make a backup of your library before trying-out this version.

[j0hannes]

Now Java just crashed when starting Jabref, core dump attached.

hs_err_pid78360.log

Note that "The crash happened outside the Java Virtual Machine in native code."

[Siedlerchr]

The exception is thrown from some network/proxy detection class in the VM. Do you maybe have an old instance of java or jabref lurking around?

[j0hannes]

I have Java 12.0.2 and the JabRef version from today.

[juejung]

@tobiasdiez Thanks, it works again under:
Ubuntu 18.04 with Gnome desktop with the latest .deb build.

@Siedlerchr, you were right, the problem's gone now.
