Probably, yes. You might be getting an unexpected RuntimeException or
Error, though, which bypasses whatever you do to test for exting doGet().
You can also try hitting the "break" key (it's Control+Break in Windows, and
I think it's Control+Y in Unix) in the window that's running Tomcat: that
will show you the state of all the running threads.
