This is the similar way to kill any responsive or unresponsive server/executable.
On MAC:
Step 1)
ps -awwef | grep tomcat
This gets the process identifier aka pid (3rd from the list when you run the command)
Step 2)
sudo kill -15 <pid>
Kills the given process
On WINDOWS:
Step 1)
netstat -o -n -a | findstr 8080
Step 2)
taskkill /F /PID 4184
