use a BufferedInputStream with mark and reset or just reopen
the FileInputStream. If you need to access the file in a
"random" (non-sequential) way, you can use RandomAccessFile
http://java.sun.com/j2se/1.5.0/docs/api/java/io/RandomAccessFile.html
and call seek(0)

Close and reopen the file.

I would not rely on mark reset.

The docs for the marklimit method does not give a comfortable
feeling.

You need to specify the maximum number of bytes you want to
be able to go back, that's the reason why I gave alternative
ways to solve that.
