Hi Avital,

When asking questions in multiple places, it is always good to cross-link,
so people can follow the whole discussion.

The forum thread is here:
http://forum.imagej.net/t/a-problem-running-imagej-in-headless-mode/3909

And as I said there, I will be releasing a new version of ImageJ2 later
this week which fixes the issue you are having with the "--ij2 --headless
--run" syntax.

Regards,
Curtis
