I checked this and I agree that when a HttpURLConnection is connected,
ISE is thrown when you call getRequestProperties(). Then, after you call
disconnect(), getRequestProperties() returns a valid map.

This probably wasn't the intended behavior, but I don't think there is 
any upside
in changing it, given the potential for breaking running code.

I propose we change the spec. to be compatible with the current behavior.
