Tomcat cannot detect this situation, so it's unlikely to be the direct
problem. How did you come to your conclusion?

Why not? Are bugs in your application considered /features/?

What would the description be for the bug-report? "Please wait for all
application-launched threads to complete before responding to the
Maven plug-in's request top deploy a new version of my application"?
All Tomcat does is wait for in-process requests to complete, then
bring the application down, install the new one, and bring the new
instance up. If you have a thread doing something else, Tomcat will
not stop it, wait for it, or otherwise interrupt it (unless you have a
ServletContextListener which waits for it to stop during shutdown,
which you absolutely should be doing).

NB: To Calder's point, you /did/ start another thread whether or not
you realized it. Your "SOLVED" message(s) lack the proper SMTP
headers[1] to get the messages properly threaded. It's not a big deal
for real-time readers, but it's quite important for the mailing-list
archives which are very valuable to people who have your same issue
but aren't reading about it /today/.
