8080 port already taken issue when trying to redeploy project from Spring Tool Suite IDE

I have strange thing when I try to modify Spring project inside my Spring Tool Suite. On the first load (deploy) everything is fine, application compiles and runs on localhost:8080

When I change something inside code and try to redeploy it (Run it again – Run As Spring Boot App) I get error message

*************************** APPLICATION FAILED TO START


Description:

The Tomcat connector configured to listen on port 8080 failed to
start. The port may already be in use or the connector may be
misconfigured.

Action:

Verify the connector’s configuration, identify and stop any process
that’s listening on port 8080, or configure this application to listen
on another port.

o.s.j.e.a.AnnotationMBeanExporter : Unregistering JMX-exposed
beans on shutdown

If I shutdown process on that port manually everything works fine again, but this can’t be right way of redeploying Spring app. Am I doing something wrong here?

I’m using :: Spring Boot :: (v1.4.1.RELEASE)

P.S. I’m aware that I can setup some kind of hot-swap mechanism to have automatic reload of page after I change code, but for now I would like to resolve this issue first.

Thanks for any kind of help or info.
