The IOException --> "Invalid Http response" is what I get as soon as the getInputStream() method is called. It seems like the method had been improved an is much more sensitive, meaning that responseCode=-1 result is not specifically checked in Java 1.6.

Get the menu on one of the HTTP-carrying frames, and select "Follow TCP 
Stream".  What is the result?  Does it look like a proper HTTP exchange?

I would suggest calling getErrorStream() if you get an exception from 
getInputStream(), but if the response does not appear to be valid HTTP, 
I can't predict what getErrorStream() will actually give you.
