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.

Done! Took 0.1s

All scores:

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.

"My version" is also a little bit old, I will publish a recently updated one, hope that it can solve your problem.

thanks, looking forward to a new version

I updated the RoboRunner page to add the link to the fork. You can try and see whether it solved your problem.

Thanks. I already using and it it works.

Could you enable issues in your github repo, in case there are problems to report?

Done. It seems that issues aren’t enabled by default for forks ;).
