RoboRunner freeze

Hi, could you help with your version of RoboRunner from github.

I use to use User:Voidious' version and was fine until several years ago. This year (2023) I tried to run it but it just freezes. Then I switched to your fork, it also freezes but at least produce some output to post.

I tried to run wit openjdk 11 and 17, the results are similar.

Side note I could gradle your version only with openjdk-11.

I suspect that it is all due to jdk change, since it also broke Voidious' version which use to work just fine. But I cannot spot what is wrong.
