Is there any way to see more information on who initiated a Java thread?

Question

I recently had a single Java thread out of my confluence instance run away from me. Using top -H, I could see that this thread was consistently running CPU usage up to 99.9% while all the others appeared normal.

Is there any way I can map this thread to a single user or to a single IP address or to a single task. Perhaps next time this happens I can ask the user to stop what they are doing and log out rather than restart the entire Confluence service for everyone.

For the googlers,

I found this script elsewhere and it did the trick:

#!/bin/bash
PID=$(top -n1 | grep -m1 java | perl -pe 's/\e\[?.*?[\@-~] ?//g' | cut -f1 -d' ')
echo The PID of the Confluence process is $PID
TID=$(top -n1 -H | grep -m1 java | perl -pe 's/\e\[?.*?[\@-~] ?//g' | cut -f1 -d' ')
echo The PPID of the highest CPU consuming Java thread is $TID
NID=$(printf "%x" $TID)
echo The hex value of the highest CPU consuming Java thread is $NID
if [[ $PID -gt 0 && "$NID" != "0" ]]; then
        sudo /usr/java/jdk1.6.0_20/bin/jstack $PID | grep -A500 $NID | grep -m1 "^$" -B 500
fi;

echo -n "OS thread count is: "
ps -eL | grep java | wc -l

echo -n "Open file count is: "
sudo /usr/sbin/lsof | grep java | wc -l

echo -n "Total established connection count is "
sudo /usr/sbin/lsof -i | grep java | grep -i established | wc -l

echo -n "HTTPS incoming connection count is: "
sudo /usr/sbin/lsof -i | grep java | grep -i established | grep :https | wc -l

echo -n "Total other (outgoing) connection count is: "
sudo /usr/sbin/lsof -i | grep java | grep -i established | grep -v ":https" | wc -l

echo -n "Database (outgoing) connection count is: "
sudo /usr/sbin/lsof -i | grep java | grep -i established | grep "dbServer" | wc -l
