Yep, you wouldn't.  That package is part of WBEMServices which
has been modified for use in our product.  A client socket
factory has been added but all it does is delegate to the
default factory and then call setSoTimeout().

Oooooh, nice catch!  I hadn't thought of that one.  The key
of course is, where might the 'somewhere' be?  But at first
blush that theory seems a lot more plausible because we're
doing nothing on the server side that should result in a
fixed port number.

We're still struggling to reproduce the problem in-house but
I'm going to add a little more logging to try to detect that
situation if it occurs.  Thanks, Peter!
