The urlconn branch does not introduce extra caching, it just avoid relying on the URL details. What is calling URL.openStream in this trace?

A VirtualFileURLConnection.getInputStream cache might be one cache to introduce. The AbstractURLHandler.openStream would be the other place. The main problem will be making sure these streams are closed to avoid leaks/locks.
