Java 6 Copying files with readline

I am trying to copy files with some required parameters: inputEncoding , outputEncoding and outputLineSeparator .

But when I run my following code, my final CRLF char file is not copied well, this last CRLF char disappears.

I think readLine returns null after line 3 because line 4 is empty ...

My goal is to find a copyfile function that can strictly copy these two next files.
Is there a way to copy also this final empty string (last newline char)?

Thanks in advance for any help.

Input Files
File testInEndNL.txt (explicit char)

A<CRLF>
B<CRLF>
C<CRLF>

      

        
        
        
      

    

TestOutEndEOF.txt file (explicit char)

A<CRLF>
B<CRLF>
C

      

        
        
        
      

    

Output files
File testOutEndNL.txt (explicit char) KO for me

A<LF>
B<LF>
C

      

        
        
        
      

    

TestInEndEOF.txt file (explicit char) OK for me

A<LF>
B<LF>
C
