Here's what's going on: I currently own and run a small CraftBukkit Server that I host on my desktop computer (see specs below) at my home and, for the most part, everything generally runs smoothly on the server.
However, a thunderstorm rolled through my area earlier today so I had to disconnect everything. I properly shutdown the server via cmd with the stop command and properly shutdown my computer and everything. After the storm rolled through, I connected everything back up, ran the run.bat file that starts the server, and then, all of a sudden I start getting random errors. Sometimes this happens so I didn't think much of it because it was the same general error that usually pops up time to time. I try connecting and it worked, I started working on the spawn and a short time later it timed out. I disconnect, tried re-connecting again and no luck. I issued the stop command on the console, started it back up and the same error happened again but only this time I couldn't connect at all. I ran this cycle a few more time and eventually gave up.
Here's the console log on startup:

Note that there are a few IOExceptions here and there, I'm not sure if those have anything to do with the server suddenly timming out at every startup or not. The IOExceptions have always been there and reakky haven't caused any troubles as far as I can tell.
Here is the crash report as well:

As you can see in the crash report, I use Windows XP (SP3) with about 3GB RAM, about 80GB HDD (yes I know, it's old and decrepit) Intel Pentium 4 processor.
I have also deleted the run.bat file and created an identical one. It didn't make a difference since I still got the same type of error during startup.
So does anyone know how to fix this? Is it the fact that the computer is too old or is it within java or is it just simply my internet? (I have Fiber Optic Internet with a 5Ghz Wi-Fi connection speed)
