I assume that this happens when you try to save a model? Do you get this only in Auto-WEKA or also for other models?

I am having the same problem.
Specifically, this problem arises both if I click the "start" button both in the Auto-WEKA tab and in the Classify tab. I have no problem to save models in weka, I get this only in Auto-WEKA (as far as I know).

It seems to be caused by the version of java virtual machine. Work-around for macOS: https://qili.site/en/auto-weka-issue/
