JabRef-3.8 not running correctly

Hello,
JabRef-3.8.2 does not run anymore, only using command line and three ‘enter’ makes it work (see result below).

openjdk version "1.8.0_131"
JabRef-2.10 starts in a normal way.

Any idea?

Thanks
S

[then three ‘enter’, the three lines follow and Jabref opens]
