Hello, my group's submission for the gamejam (https://itch.io/jam/korge-gamejam-1/rate/672309) received a comment saying all it displayed was a black screen. We have updated the submission with a jar tested on our computers and a few others running jre8 from the oracle website. One of them didn't work and was giving "java.lang.Error: Invalid memory access" Exceptions in the console until java was updated.
