Tim Allison commented on TIKA-3561:
-----------------------------------
Wait, now I see the problem. I had unzipped the attachment and was processing
just the xlsx. I'm still able to parse the full thing with -Xmx6g.
The problem is that the PackageParser calls POI on the stream of the embedded
xlsx, so POI slurps the full thing into memory because it doesn't have the
"file" available. I wonder if we should modify the packageparser to cache the
stream to disc in a temp file if it is above a certain size...or perhaps do the
caching to disk in the OOXMLParser?
