The following code illustrates unexpected
behavior when dealing with a drive's root
directory on Win 95. Creating a File using
C: or C:\ does not work properly. It is
understandable that C: would not work (although
its manner of not working is bizarre), but
C:\ should work. More details in the comments
within the code.

// Illustrates JRE 1.1.3's unfortunate behavior on Windows 95. Run from
// some directory other than c:\ for best results.

public class pain
{
   public static void main( String args[] )
   {
      File f1, f2, f3;
      String contents[];

      // Three ways of specifying the C drive.

      f1 = new File( "c:" );
      f2 = new File( "c:\\" );
      f3 = new File( "c:\\." );

      // Note the interesting absolute path for f1.

      System.out.println( "f1: " + f1.getAbsolutePath() );
      System.out.println( "f2: " + f2.getAbsolutePath() );
      System.out.println( "f3: " + f3.getAbsolutePath() );

      // f1 gets the right number of files despite its weird absolute
      // path.

      try
      {
         contents = f1.list();
         System.out.println( " Num in f1: " + contents.length );
      }
      catch ( NullPointerException e )
      {
         System.out.println( "f1.list() is null" );
      }

      // f2 thinks there are no files in c:
      try
      {
         contents = f2.list();
         System.out.println( " Num in f2: " + contents.length );
      }
      catch ( NullPointerException e )
      {
         System.out.println( "f2.list() is null" );
      }

      // This works.

      try
      {
         contents = f3.list();
         System.out.println( " Num in f3: " + contents.length );
      }
      catch ( NullPointerException e )
