[TIMOB-2798] Android: xhr NPE for posts with empty http body

I have a page that returns a 200 response, but nothing in the body.

var xhr = Titanium.Network.createHTTPClient();
xhr.onload = function()
{Ti.API.info('I am in utf-8 onload for POST');};
xhr.onerror = function()
{Ti.API.info('I am in utf-8 error for POST');};
xhr.open("POST","http://mywebsite.com/script.cfm");
xhr.send({"a":"hi", "b":"there"});

If the sript I post to doesn't return a body, only a 200, then the NPE happens. If I change the script to return any text at all the NPE is avoided.

The resulting log of the NPE looks like:
