The iText class PdfStamper does not have a method extractRevision. Unless
your pdfStamper is an instance of something entirely else, your code
execution stops no later than here.
Furthermore, if you re-open the file, I would expect you to use a PdfReader.
Thus, your description somehow does not make sense. It might help,
therefore, if you provided a SSCCE <http://sscce.org/> illustrating your
issue.
This all being said,

No, the InputStream is not empty, your interpretation of the available()
method is wrong.
available() "Returns an estimate of the number of bytes that can be read (or
skipped over) from this input stream without blocking" (cf the InputStream
JavaDocs). So it is a) only an estimate of b) bytes readable without
blocking, not bytes overall. Thus, it doesn't say anything about the bytes
that can actually be read.
In the case at hand, the InputStream returned is a
com.itextpdf.text.io.RASInputStream which does not override the default
implementation of that method which always returns 0.
You can simply read the revision from that stream.
