Summary: Incorrect NullPointerException in java.io.File.listFiles

Initial Comment:
The following code fails at runtime, while it works
with Sun's java 1.3 and gij.
The code just tries to list the files in an empty, but
existing directory:

import java.io.*;

class Bug
{
  public static void main(String[] args)
  {
    File f = new File("/tmp/Empty");
    f.listFiles();
  }
}

Make sure /tmp/Empty is an existing, empty directory.
