Solved Bungee Startup Error: Failed to create child event loop...

Hi, so my BungeeCord server has been unable to start lately. I haven't been able to figure out what was causing this, because it just randomly started happening. On startup, my Bungee server outputs the following error...

Code (Text):

I googled the issue, and could not find anything on it. If you've had this issue before, and have any idea how to solve it, that would be great.

EDIT: This has been solved, this is how I fixed it...

All I had to do was change the java version to java 1.8, for some reason that fixed it for me.
