    So i'm getting this logged to my terminal when I try to execute the jar. I use ubuntu 17.04 and it was working fine before until I installed openjdk-9 through the package manager. I deleted all of the openjdk packages and reinstalled each one by one and tried executing each and I always get this error. I tried the oraclejdk-9 as well with no avail. I've also tried to deleted all of the dot files as well before re-installing. Nothing works. Here is the full stack trace. Thanks in advance.
