Java.exe process spikes to 100% during the day, and I need to know why

Max point granted!!!

I am not a Jboss person, but in viewing the server.log file, I show an error (screenshot attached). I am new to the Jboss Server world, as I just recently stepped into a new job that require me to learn the product. I need help with troubleshooting the error, and what it means that cause the java.exe to increase to 100%. This is a web server that has ties to New Platform, and IVAN. Client make connections to it and sometimes get an error and cannot log into New Platform because the CPU spikes up to 100% during a certain time in the day. To mitigate this issue, I'm left with stop/starting the Jboss service or rebooting the server. I need to get to the bottom of it, and troubleshoot the Jboss, Java aspect of it. First, can anyone tell me what the error means? I cant find anything in google.

There's lots of possible causes. I'd suggest step 1 is hooking up a profiling tool so you can see what the process is doing when this next happens. Where is it spending it's time? That should help identify the possible fix.

The profiler I like these days is visualvm: http://visualvm.java.net/

Free and you can connect it to a running process.

I installed visual vm on my local win 7 computer, and made a remote connection to the server with the issue. However, it only shows the IP of the remote console, but no java app or process. What should I do next? Is there a better app or tool that will tell me more about the Jboss connection or java process?
