Hi Richard,

Ah, sorry, I missed the code in your original post.

You can verify that ImageJ is using Java 9 by following these instructions:
http://imagej.net/Troubleshooting#Checking_the_Java_version

It looks like you wrote "--java_home" instead of "--java-home" (i.e.,
underscore instead of dash), so perhaps that is your problem.

That said, I have not tested it myself, so it still might not solve it...
either way, would be nice to hear back on this thread about how things go!

Regards,
Curtis
