Release Note: Modified HttpURLConnection behavior when no suitable proxy is found

The behavior of HttpURLConnection when using a ProxySelector has been modified with this JDK release. HttpURLConnection used to fall back to a DIRECT connection attempt if the configured proxy(s) failed to make a connection.
This release introduces a change whereby no DIRECT connection will be attempted in such a scenario. Instead, the HttpURLConnection.connect() method will fail and throw an IOException which occurred from the last proxy tested.
