Re: HTT URLConnection.getInputStream seems broken in cvs

[Fabio Roger <fabioroger at gmail dot com>]

yes. the problem happens when the gnu.java.net.protocol.http.Headers
tries to parse the response.

in fact the bug only happens when trying to download one specific file.
I put this file here http://fabio.k2infinity.com/test.hdr and this code
triggers the bug:

public class Test {
   public static void main(String[] args) {
      try {
         new URL("http://fabio.k2infinity.com/test.hdr";).openStream();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}

I tried putting the file here http://dinavis.net/test.hdr but
downloading from that site the bug does not come up.

and this code works fine in gcc 3.4 .. it only throws the exception in
cvs HEAD.
