Mark, I used it in the patch I just sent to Alexander Kitaev for a problem
he turned up while using SVNKit (dev@ is CC'd on the discussion).

To the best of my knowledge, java.net.URL doesn't establish a network
connection until its openConnection() method is called, and I didn't notice
anything at odds with that expectation in its documention [1]. Do you know
something I don't? :-)

This is a trivial method, so I'd be fine switching to any other
implementation which obeys the test case I provided (e.g. URI [2], perhaps?).
