my java is broken !

I wrote a loop to read a 26000 character text file NVRAM.TXT into a
character array. It worked fine. The program is listed below. It has
only 24 lines. Today when I run it, it has weird errors referenced to
line numbers 2442, 2685 and 1620. When I click on those error messages
it shows lines in a completely different program - a program that I
never wrote for sure. I saved the file with a different name and it runs
fine with that name - no errors. The file name that has the problem is
Nvj5. That is the file selected and displayed when I click RUN FILE. It
is the file listed below. Even though it is selected and displayed when
I click RUN FILE my system is running some other huge file instead. Has
anyone ever heard of a problem like this?

import java.io.*;

public class Nvj5 {

     public static void main(String[] args){

         try {
         FileInputStream file = new FileInputStream("NVRAM.TXT");
         char[] nvchr = new char [30000];
         int fin = 1;
         int count = 1;
             while (fin != -1) {
              fin = file.read();
              nvchr[count] = (char) fin;
              System.out.print(nvchr[count]);
              count++;
             }
         System.out.println("Bytes read : " + count);
         file.close();
     } catch (IOException e){
         System.out.println("Could not read file");
     }

     }
}
