Hi Jiri,

>but then I got just this error message:

It looks like something was broken running Fiji from the command line in
general, and not explicitly related to scripting. I would recommend
developing your script in the script editor
<http://imagej.net/Using_the_Script_Editor> for now if you can.

I created a bug report <http://fiji.sc/bugzilla/show_bug.cgi?id=964> to
track the issue. We're at the end of a long overhaul of Fiji to bring all
of its components to a truly stable state, so I assume some version skew
crept into the live version, causing the specified class not to be found.

>IJ.exit()

Just a side note that there is no exit method in the IJ class
<https://github.com/imagej/ImageJA/blob/master/src/main/java/ij/IJ.java>.
But I can, for example, IJ.log in the script editor with no problem.

Apologies for the inconvenience. Thank you for reporting it though!

Best,
Mark
