Stephen Duncan Jr commented on TIKA-521:
----------------------------------------
I have 7MB files that can't be handled when giving 2GB of RAM, it required 3GB
to process. I'm looking at likely needing to run on 32-bit Java, so increasing
the heap size that high is not really an option. Besides, at the growth rate I
see, a 20MB file might require 10GB of heap. That simply doesn't scale for
reasonable file sizes. Meanwhile, the same 7MB file can be parsed using the
alternate API using 128MB for the heap size. That should allow any reasonable
file to be processed assuming a reasonable 1GB heap size.

> I have several XSLX files I'm trying to parse with Tika that are failing with
