program does not open after system update to Mac OS 12.1 monterey

[oeco28]

Hello,
I had tappas installed but it has not worked after I updated the system to Mac OS Monterey on an intel machine,
if I run tappas from the command line (java -jar tappas.jar), I get the following error:

Error: Could not find or load main class tappas.Tappas
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

I had java 8 build 321 and it didn't work. I then downgraded to 222 and it still doesn't work. But I don't have a good sense for why it is not working.
anybody experiencing similar problems?

Hi @oeco28,

Even though your question was answered via email, I'll just post my answer here in case someone else experiences the same issue.

Unfortunately, we have never seen such compatibility issues and don't have that much experience debugging on Mac, so this is a hard one to fix -we would need access to a computer with the same OS update as yours to see if we can reproduce the error, which we are not sure how to get a hold of right now.

Most of us at the lab work with Ubuntu machines so, in the meantime, what we can recommend is to set up a virtual machine with Ubuntu and run tappAS there -tappAS runs smoothly on Ubuntu 20.04 with Java 8, so that shouldn't be problematic.

I'll keep the issue open until it is fixed.
