I added around 5-6 external tomcat servers with various configurations. I
created a J2ee1.4 app with a button and deployed it on tomcat5.5.17. Then I
changed the target server of the application without stopping the first server.
When I look at the icons of the server nodes in the runtime tab all of them are
running.  

Steps to reproduce:
Use a fresh user dir:
1.Add 2 or more external tomcat servers.
2.Create a new VWP project with one of the Tomcat5.5 servers as the target.
3.Place a button on the page.
4.Deploy the application
5.Without stopping the first tomcat server change the target server of the
project to another tomcat5.5 server.
6.Run the application.


At this point ideally it should give an error that there was a port conflict
since an instance is already running at that port.
Instead the application runs and shows the page in a browser.

Now if you check the servers node in the runtime tab you will see that all of
the servers show a green running icon on them. In addition the all server nodes
can be expanded to view their web applications. Even though they show the same
applications.

If you stop any one of them it will stop the first server and you wont be able
to open the page in browser even though the first server node will show that it
is running.

Interestingly the glassfish node does not show that it is running. I am
attaching the screenshot of the server nodes as well.
