Andrew Jackson commented on TIKA-900:
-------------------------------------
I re-uploaded the patch as it had an extra format that is not necessary for
this patch. Also I noticed a typo in my original issue description. The offset
should be 32769, not 37633.

> I have been testing Tika's ability to identify ISO9660 disk image file
> systems, and discovered two problems. Firstly, the offset match matcher was
> wrong (37633 instead of 37633). Secondly, and more seriously, it was
> impossible for that signaure to ever match, because the default buffer size
> was far to small. It is currently set to 8KB, and as this signature is some
> 36KB into the file, Tika could never find the match. The attached patch fixes
> the magic, and extends the buffer to 64KB.
