HttpClientURLConnection breaks the TCK

As this does not match the behaviour of the JDK HttpUrlConnection some tests in TCK7 no longer work. The particular behaviour in this case is that GET requests are not automatically changed to POST requests if doInput is called, however looking at the class it looks like there is a massive amount of behaviour that is not consistent.

This is a big problem, as any customer that is relying on the behaviour of the JDK client have to modify their application.
