At times an application do not stop properly and keep running in background, occupying  port.
       
Step 1: Identify the TCP process id binding to a specific port
$>netstat -ano | find "8080"

  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       28268
  TCP    [::]:8080              [::]:0                 LISTENING       28268

Step 2: Kill the process
$>taskkill /F /PID 28268

Following is the method which caused the exception @Transactional(propagation=Propagation....
