File.exists() does not work on files > 2GB. It doesn't work on JDK1.2.1_03
and up. It works on JDK1.1.6.

Instructions to reproduce:

1) mkfile 2050m twogig
2) Compile and run java program below:

import java.io.*;

public class FileExists {

        public static void main(String argv[]) {

                File fl = new File("/export/file_exists/twogig");
                
                if (fl.exists())
                        System.out.println("Exists length - " + fl.length());
                else
                        System.out.println("Doesn't exist");
        }
}
