      Description

      Licensee reported us that behavior of HttpURLConnection.getResponseCode() is
      different between 1.3.1 and 1.3.1_01. It seems to happen after implementation of
      #4160499. This problem appears on Solaris and Windows.

      - behavior of getResponseCode() included in JDK1.3.1 older
        When HTTP server returns HTTP responce, Java receive the responce code as
        server returned.


      - behavior of getResponseCode() included in JDK1.3.1_01
        When HTTP server returns code over 400(?), Java throw the exception. Detail of
        exception is uncertain.

      We tested this matter by using followin sample code on Windows. In the case of
      access to exsiting server, difference donesn't appear. But in the other case, some
      differences appear.
