Sadly your modification only works in a restricted scenario. Only one
reference to sign for inputstream. The getReseteableInputStream()
tries to do what you are doing, but it only works with
ByteArrayInputStreams, I have try to make it work with a
FileInputStreams but a entry in bugzilla stated my faillure.
But I welcome any new try.
