That didn't seem to have any effect at all. But after futzing around 
with it for two hours yesterday, a solution finally occurred to me:

Our current version instantiates and connects the SSLSocket in one swell 
foop:
> SSLSocket s = (SSLSocket)factory.createSocket(adr, port);

If instead, I instantiate it and connect it in separate steps, I can 
then do a setEnabledProtocols() on it (if we're running under Java 7) 
BEFORE we connect it.
