java -version:

java version "1.2.2"
HotSpot VM (1.0.1, mixed mode, build c)

Run the following program (tested on NT, alter the filenames to
match a real file on your local disk, e.g. *.txt):

---------------------%<-----------------
import java.io.File;
import java.net.URL;
public class FileURLConnectionTest extends Object {
  public static void main (String args[]) throws Exception {
    String test = "d:\\temp\\nrlog.txt";
    System.out.println (test + '\t' + new File (test).toURL ().openConnection ().getContentType ());
    test = "d:\\temp\\";
    System.out.println (test + '\t' + new File (test).toURL ().openConnection ().getContentType ());
    test = "d:\\temp";
    System.out.println (test + '\t' + new File (test).toURL ().openConnection ().getContentType ());
    test = "file://localhost/d:/temp/nrlog.txt";
    System.out.println (test + '\t' + new URL (test).openConnection ().getContentType ());
    test = "file://localhost/d:/temp/";
    System.out.println (test + '\t' + new URL (test).openConnection ().getContentType ());
    test = "file://localhost/d:/temp";
    System.out.println (test + '\t' + new URL (test).openConnection ().getContentType ());
  }
}
-----------------%<---------------

Output I received:

------------------%<-------------
d:\temp\nrlog.txt text/plain
d:\temp\ text/html
d:\temp text/html
file://localhost/d:/temp/nrlog.txt text/plain
file://localhost/d:/temp/ text/html
file://localhost/d:/temp content/unknown
------------------%<-------------

For the case of the directories, an HTML directory listing is
produced by the connection, so the content type should be
text/html.

There appear to be two problems in the class sun.net.www.protocol.file.FileURLConnection:

1. In initializeHeaders(), if isDirectory is true, then the line is run:

properties.add(CONTENT_LENGTH, TEXT_HTML);

which should instead read:

properties.add(CONTENT_TYPE, TEXT_HTML);

This probably accounts for the content/unknown instead of the desired
text/html return for the last item.

2. That there is a discrepancy between the last two items is
strange, I did not see an explanation.
