Don't report the hashcode of our error message key into the properties file as the vendor error code.  This number is completely random and undocumented and ties us into using the current error message keys and implementation to maintain the same codes.  Further error messages from the server will not provide this value, so it's best to leave it alone entirely and tell people to use getSQLState().
