There are some process which does not shown using normal netstat command, so you have to check it using sudo.

Do sudo netstat -lpn |grep :8080. Process running by system does not show PID, to get PID of this process you will have to run it using sudo

And then killl the process using port 8080. You may have to use sudo here as well. So to kill this process use sudo kill -9 PID
