Still a WIP, I had to restart the script a few times, it's a bit of trial and error in this case. I was initially able to reduce the code by a large margin, but it still took a long time to run. Now I am trying to reduce the memory available with `-XX:CompileCommand=memlimit` to see if we can make it fail faster @eme64.
