Hi,

This has three possible problems I see:

- on MacOSX, Java is based on Aqua, not X. But I have not yet checked if
  ImageJ can run headlessly on these. Will do so later today, and keep you
  posted.

- on many clusters, you do not have enough quota to install Xvfb.

- for some setups, there is no readily available Xvfb package (since a
  cluster is _meant_ to run without X11), and it can cause real trouble to
  compile it yourself for these, especially where gcc is not installed.

All in all, it feels not really clean, having to install a (virtual)
graphics environment, in order to run without (a non-virtual) one.

Ciao,
