Newline characters stripped out

[mystcmage]

HttpMocaConnection is stripping out the newline characters with this line:
final String responseBody = in.lines().collect(Collectors.joining());

I suggest replacing it with:

    		StringBuilder buf = new StringBuilder();
    		int charsRead;
    		char[] cbuf = new char[1024];
    		while ((charsRead = in.read(cbuf)) != -1) {
    			buf.append(cbuf, 0, charsRead);
    		}	
    		final String responseBody = buf.toString();
