Stanley wants to use httpsClient with a specific proxy set. He's
trying to use the undocumented constructor. It's pretty obvious
where the exception lies, since sslSocketFactory is never set,
it's throwing the exception from:

factory.createSocket(host, port);

I don't think it's simply a matter of setting the factory, but we
can explore this when we get to this bug.

He's getting the following null pointer Exception.
