I've discussed this with Scott and we're agreed we will go with the 
minimal change to the shared
code to begin with. I have created a CR (7131142) to track providing 
what the Apple code did
originally, which was that it dynamically updates the system proxy 
properties. The best way
to do this is through the DefaultProxySelector class rather than in the 
common property initialization
code though.
