Server Issues: Internal Server Error

[Toothbrush123]

Hi! So I've been running an AOTBT server for a few days now for just me and some friends, and it's been working like a charm. Except today, I load up the server, nothing out of the ordinary, and then when we try to connect, we all get a, "Disconnected by Server: Internal Server Error" and I have no idea what's causing it. Deleting the player data seems to fix it, but that means restarting completely and I'd like to know if there's a fix for this that doesn't include starting from scratch. Thank you!

 

P.S. Here's the startup log for my server: http://pastebin.com/cMmXxGCg

And here's the only crash report I have: http://pastebin.com/V3rL1ush

As an experiment, could you roll back to an earlier version of Java and try it again?

I totally would, but I'm not entirely sure how to do that. Is there a place I can download a previous version of Java?

try an older Java 8 x 64. I'm wondering if a recent update messed you up.

Just installed the later update, no changes. Darnit.

Also, whenever I attempt to connect, in the console it says. "Reached end of stream for 127.0.0.1" and then "Reached end of stream for 192.168.0.1".
