Created attachment 1677
  --> https://icedtea.classpath.org/bugzilla/attachment.cgi?id=1677&action=edit
the jnlp file that I use (url obfuscated for security reason)

I have 2 X server running : one when I'm in front of the computer, one when I
connect from distance through xrdp
I run openbox when away
I have this error : "Headless check failed" when I run "javaws myjnlpfile" even
in urxvt inside openbox
it seems it didn't succeed opening a jwindow()
it works fine when I run the same command inside urxvt with lxqt when being in
front of the computer

application to launch : Univiewer from Automic (can't provide the jar :/)
