RuntimeException when running on MacOS

[amedyukhina]

Hi, I wanted to try out your plugin, but I get an error when starting it.

This is what I get in the Exception window:

And is what is printed in the Console:

I am not developing this plugin anymore and haven't touched it for a while.

The error looks like JavaFX is not present on your Java installation. JavaFX is required for the plugin to work (it provides the GUI).

I remember that was an issue already when I was developing the plugin. See there for details: https://forum.image.sc/t/fiji-wont-start-after-adding-an-update-site-filamentdetector/10436/8

Hope it helps!
