[Bug classpath/22778] URLConnection.connect does not work on directories

[gcc-bugzilla at gcc dot gnu dot org]

With an URL (file protocol) representing a local existing directory, the
connect() method fails with java.io.FileNotFoundException: /tmp/bug/. is a
directory
(tested with kaffe, sablevm and gij 3.4 on Debian GNU/Linux).
gij 3.3 does not fail on connect, but it does if you later try to open an
InputStream from that URL.

On all Sun JVMs I could try (1.3, 1.4 and 1.5), connect() works. Furthermore,
it's possible to read from the connection. There is some difference there. 1.3
prints  html code (like what you'd get from a web directory listing). 1.4 and
1.5 return one line for each file in the directory. I think it would make the
most sense for classpath to behave the same as 1.4 and 1.5.

Here is a minimal testcase:

public class Bug
{
  public static void main(String[] args)
  {
    try {
      java.net.URL dir = new java.io.File(".").toURL();

      java.net.URLConnection con = dir.openConnection();
      // Connect should work on an existing directory
      con.connect();
      System.out.println("OK, content:");

      // Print the stream associated with the URL
      java.io.BufferedReader in = new java.io.BufferedReader
        (new java.io.InputStreamReader(con.getInputStream()));
      String line;
      for (; (line = in.readLine()) != null;)
        System.out.println(line);

    }
    catch(java.io.IOException e) {
      e.printStackTrace();
    }
  }
}
