The splitting of the note into @apiNote and @implNote mostly looks good. 
I think it should be "cached by the Java virtual machine" rather than 
"cached internally". It would be good to fix inconsistent line length 
while you are there.

I still think we need to find a better name for SystemProperty and it 
would be good to re-visit how this is initialized in initPhase1. I think 
this is Stuart's point too. It would be nice to call it with "props" so 
that it captures the initial value of the interesting properties. A 
second best would be to a SystemProperties.capture() or something explicit.

There's something not quite right with the change to SocksSocketImpl 
that I mentioned in the other mail.
