Oops, forgot to copy this to the list.

Windows XP Home and Sun JVM 1.5.0_09.  However, if I run a very simple
program that just calls HttpClientManager.init() the problem doesn't
happen.  Therefore I think that one of the libraries that I use in my
more complex application is setting the http.proxyPort property to the
empty string internally.  I don't think this is a function of my OS or
JVM.
