File size limitation question

Hi all,

As I found, maximum file size explicitly limited in Jigsaw (2.2.5a discussed).

org.w3c.tools.resources.FileResource.java (line 343):
     setValue(ATTR_FILE_LENGTH, new Integer((int)file.length()));

Conversion from java's standard Long for file sizes to Integer is done.
I wonder why, as this makes impossible for Jigsaw to handle files with
size more than 2^32 bytes (4GB).
In my case this is unacceptable...=(
(I'm thinking about replacement all of that to Long, so it's important
to know why it was done.)

Best regards,
Andrey Yakovenko
